MOISTURE AND EXPOSURE CONDITIONS

To ensure optimal performance in various environmental conditions across the United States, we have chosen to adopt the classifications of National Design Specification for Wood Construction (NDS) and the AC257 acceptance criteria by ICC-ES. The dry classification includes environments where humidity is limited and corrosion risk is minimal (e.g. indoor or protected spaces). The wet classification covers environments with high humidity exposure, such as outdoor areas or locations with direct water contact. AC257 also introduces specific criteria for corrosion resistance in chemically treated environments or in coastal areas exposed to salt. The summary table considers AC257 Exposure Conditions 1 through 4, ensuring that selected screws provide optimal performance and durability in diverse usage conditions. The moisture content of wood significantly affects the mechanical properties, strength, and stiffness of structural members. In the design of wood connections, standards like the NDS (National Design Specification for Wood Construction) and CSA086 (Canadian Standards Association) provide guidance on service condition factors. These factors account for moisture content at the time of fabrication and during service. Proper evaluation of the combined service class, wood corrosivity class, and atmospheric class is essential to ensure the structural performance and durability of connections. These classifications affect decisions such as material choice and protective measures, particularly in environments with varying humidity or exposure.

MOISTURE CONDITION According to NDS and CSA-O86

MAXIMUM MOISTURE CONTENT OF THE WOOD

DEFINITION

≤ 19% moisture

> 19% moisture

Table 11.3.3 in the NDS and Table 12.1 in CSA-086 outline the interaction of moisture content at fabrication (whether the wood is green or dried) with the in-service moisture levels. The factors vary based on the type of connection and loading conditions. Notably: • A moisture content (MC) of ≤ 19% is the threshold for “dry service conditions.”

Wet service conditions apply to wood connections when: 1. The connection is exposed to direct wetting (e.g., rain, snow, condensation) such that drying is not effective. 2. The wood member is classified as “green” upon installation and retains a moisture content above 19% until dries. 3. The equilibrium moisture content exceeds 15% averaged annually or exceeds 19% at any given time. In wet conditions, the need for moisture management is critical, as prolonged exposure above 19% MC can compromise the mechanical properties of wood and the long-term performance of connections.

If MC > 19% at fabrication or in service, adjustments using the service condition factors are applied to ensure the integrity of the structural design. For detailed application, designers should consult NDS Table 11.3.3 and CSA-086 Table 12.1, which provide the necessary correlations between moisture content, connection type, and loading conditions.

DESCRIPTION

ESR-4645 certification for Rothoblaas screws permits their design and use in wet service conditions from a structural standpoint according to AC233. However, this certification does not cover corrosion resistance requirements, which must be evaluated separately.

ATMOSPHERIC CORROSIVITY CLASSES

Corrosion caused by the atmosphere depends on relative humidity, air pollution, chloride content, and whether the connection is internal, external protected, or external. Exposure is described by the C category as following ISO 9223:2012. Atmospheric corrosivity only affects the exposed part of the connector. While the Exposure Conditions partially account for atmospheric corrosivity, it is possible to consider it separately for a more accurate evaluation, using ISO 9223 as a reference.

CLASSES

Corrosion caused by wood depends on the wood species, wood treatment, and moisture content (see page 354). Exposure is defined by the T category as indicated. The corrosivity of wood only affects the connector part inserted in the wooden element. Although the Exposure Conditions consider wood corrosivity to some extent, it is possible to assess it separately for a more accurate evaluation according to EN 14592:2022.

RESEARCH & DEVELOPMENT

3 THORNS TIP

Extensive test campaigns carried out in Rothoblaas' own laboratories and at external institutions on softwood, hardwood and LVL have resulted in the development of a performing product in every respect.

Thanks to the 3 THORNS tip, minimum installation distances are reduced. More screws can be used in less space and larger screws in smaller elements. Costs and time for project implementation are reduced.

Featuring raised slitting elements and an umbrella thread reaching the end, the 3 THORNS tip ensures a quick initial grip and easy installation, reduces torsional stress on the screw and minimises timber damage. The aesthetic finish is optimal.

Thanks to its counter-threaded slitting elements, the 3 THORNS tip facilitates insertion of the screw into the grains without damaging them. It acts as a guide hole, allowing the reduction of edge distances and screw spacing. At the same time, it prevents wooden element's cracking and mechanisms of brittle failure of the connection.

LEGEND A standard tip B standard tip (with pre-drilled hole) C 3 THORNS tip D self-drilling tip

The test is performed by tightening the screw, unscrewing it after 24 hours and filling the hole with dye to check its diffusion inside the wooden element. The portion of wood affected by the insertion of the screw is proportional to the red area.

The picture shows the insertion of screws with different tips and shows the change in pull-through depth after 1.0 second of tightening.

To be inserted, the screw must overcome the strength force of the wood. The screwing force, measured through the insertion moment (Mins), is only minimised if the tip is performing.

The graph shows the development of the insertion moment for screws with different geometric characteristics of the drill bit and the same boundary conditions (screw diameter, thread length and type, timber substrate material, applied force) as a function of the penetration length (Lins).

The accumulated torsional stress on the screw with a 3 THORNS tip (C) during its insertion is significantly lower than in the case of screws with standard tips (A) and is close to the screwing with pre-drilling hole (B).

The 3 THORNS tip (C) exhibits similar behaviour to that of the standard screw inserted with pre-drilling hole (B), tending towards the case of the self-drilling tip screw (D).

NOTES • Values in blue are from Table 10 of ESR-4645 (REDUCED CONNECTION GEOMETRY REQUIREMENTS BASED ON TESTING); • The minimum spacing and distances comply with ESR-4645, where d refers to the nominal diameter of the screw, and are valid for screw installed into sawn lumber, structural glued laminated timber and cross laminated timber;

• Wood member stresses must be checked in accordance with the corresponding Sections of the NDS; end distances, edge distances and fastener spacing may need to be increased accordingly.

GENERAL PRINCIPLES

CONNECTIONS

• Tabulated values comply with NATIONAL DESIGN SPECIFICATION FOR WOOD CONSTRUCTION in accordance with ESR-4645.

GENERAL NOTES

• To determine allowable loads for use with ASD, design loads for use with LRFD or both, tabulated values must be multiplied by all adjustment factors included in the NDS for dowel-type fasteners.

• Designed connections must respect all requirements on general principles and minimum distances.

• Tabulated values, that are referred to a single fastener, are valid for Allowable Stress Design (ASD) considering a standard loading (CD = 1.0).

• Connections with multiple screws must be designed in accordance with the corresponding Sections of the NDS and ESR-4645. • SHS AISI410 screws must be positioned in accordance with the minimum distances. • In case of combined axial and shear forces, the designer shall refer to the Hankinson formula, as specified in section 12.4.1 of the NDS, to evaluate the load-bearing capacity.

• The wood main member thickness must be greater than the screw length minus the thickness of the steel side member. • In case of steel-to-wood connection with a thick plate, it is necessary to assess the effects of wood deformations and install the connectors according to the assembly instructions.

REFERENCE WITHDRAWAL DESIGN VALUES • The reference withdrawal design values (Wref) expressed in pounds-force per inch of thread penetration into the main member for screws installed at an angle of 90° to the grain can be found in the ESR-4645. • The values for screws installed at an angle α to the grain are determined by multiplying the reference withdrawal design values with the effective thread penetration Leff of the screw in the wood member and with the factor kα: Wα = Wref ∙ kα ∙ Leff

• Z : Force-to-grain angle in the shear plane is considered as 0°. • Z : Force-to-grain angle in the shear plane is considered as 90°. • Zm : Force-to-grain angle in the shear plane is considered as 0° for side member and as 90° for main member. • Z s : Force-to-grain angle in the shear plane is considered as 90° for side member and as 0° for main member. • For the connectors inserted in the panel’s face, it has been considered the same grain direction as the layer in the shear plane. For the connectors inserted in the panel’s narrow edge, it has been considered the same grain direction as the layer in which the connector is installed. • For lateral design values the force-to-fastener angle is always considered 90°. • Typical fastener spacings are declared considering a generic load condition; spacings should be verified and defined according to the real load conditions.

CLT | WALL-TO-WALL | FLOOR-TO-WALL • The main grain direction of the CLT wall panel is always considered as vertical. • The main grain direction of the CLT floor panel is considered both parallel and perpendicular to the wall plane. • The threaded part of the screw has been always considered inserted in the central layer of the CLT panel. • The withdrawal capacity has been considered as the minimum between thread withdrawal, head-pull through and tensile strength of the screw. • According to NDS, an end grain coefficient Ceg=0.67 is considered for the lateral resistance calculation due to fastener in narrow edge of CLT.

• The main grain direction of the CLT floor panel is considered both parallel and perpendicular to the beam’s axis. • The threaded part of the screw has been always considered inserted in the central layer of the CLT panel. • The withdrawal capacity has been considered as the minimum between thread withdrawal, head-pull through and tensile strength of the screw. • According to NDS, an end grain coefficient Ceg=0.67 is considered for the lateral resistance calculation due to fastener in narrow edge of CLT. • Beam element can be considered both solid wood or glulam. • Double lumber is considered as two coupled element of 2 inches thick. • The width of the beams must comply with the minimum distance requirements. • The proposed screw’s length does not exceed the total thickness of the connection. In configurations with no declared value (-) the fastener exceeds the main member depth.

SPLINE JOINT

Where: - Wref is the reference withdrawal design value for screws installed at an angle of 90° to the grain, as shown in the table on the left; - kα factor is calculated as:

kα =

• Timber element specific gravity is considered as G = 0.42.

CLT | FLOOR-TO-WOOD BEAM

• The steel side member must have a minimum tensile strength equal to 58 ksi (400 MPa) and comply with the minimum requirements of ASTM A36.

γM

• Calculations comply with the NDS in accordance with ESR 4645.

35˚ < α ≤ 90˚

1 1.2·cos2(α)+sin2(α)

0˚ ≤ α ≤ 35˚

0.3+0.7·α 45

- α is the angle between the grain direction and screw axis. Tabulated values at page 27 are valid for Leff equal to the screw thread length b minus the tip length Lt and kα = 1 for α=90°, kα = 0.91 for α= 45°, kα = 0.3 for α = 0°. • The minimum embedded thread length is 6 times the outer thread diameter for screws installed at 90° to the grain, unless otherwise noted. • The minimum embedded thread length for screws installed at an angle 0° ≤ α < 90° to the grain is 8 times the outer thread diameter, unless otherwise noted. • At least four screws must be used in a connection with screws installed in the wood member with an angle between the grain direction and screw axis α ≤ 15°.

• Spline thickness is considered to be thinner than the top CLT layer. • For Root Diameter d 2 >0.25 inch, the bearing strength of the spline is conservatively considered as 3350 psi according to NDS. • The main grain direction of the CLT floor panel is considered both parallel and perpendicular to the spline’s direction. • The width of the spline and consequent machining on CLT panel must comply with the minimum distance requirements.

HALF LAP • The main grain direction of the CLT floor panel is considered both parallel and perpendicular to the machining’s direction. • The width of half-lap machining on CLT panel must comply with the minimum distance requirements. • The proposed screw’s length does not exceed the total thickness of the connection.

BUTT JOINT

• The reference withdrawal design values must be inferior to ftens of the screw.

• The screw is considered inserted with an angle of 45° between the screw’s axis and CLT plane face.

REFERENCE HEAD PULL-THROUGH DESIGN VALUES

• According to NDS, an end grain coefficient Ceg=0.67 is considered for the lateral resistance calculation due to fastener in narrow edge of CLT.

While designing a connection the head pull-through values must be compared with the tensile resistance of the screw and, if necessary, thread withdrawal. The lower value is the governing one.

• The axis of the connector on the shear plane is considered to run through the central layer of the panel.

COUNTERSUNK SCREW 3 THORNS TIP Thanks to the 3 THORNS tip, minimum installation distances are reduced. More screws can be used in less space and larger screws in smaller elements. Costs and time for project implementation are reduced.

FAST With the 3 THORNS tip, screw grip becomes more reliable and faster, while maintaining the usual mechanical performance. More speed, less effort.

JOINTS WITH SOUNDPROOFING PROFILES The screw has been tested and characterised in applications with soundproofing layers (XYLOFON) interposed on the shear plane. The impact of acoustic profiles on the mechanical performance of the HBS screw is described on page 86.

NEW-GENERATION TIMBER PRODUCTS Tested and certified for use on a wide variety of engineered timbers such as CLT, GL, LVL, OSB and beech LVL. Extremely versatile, the HBS screw guarantees the use of new-generation woods for the creation of increasingly innovative and sustainable structures.

TIMBER | HBS | 49

GENERAL PRINCIPLES

CONNECTIONS

• Tabulated values comply with NATIONAL DESIGN SPECIFICATION FOR WOOD CONSTRUCTION in accordance with ESR-4645.

GENERAL NOTES

• To determine allowable loads for use with ASD, design loads for use with LRFD or both, tabulated values must be multiplied by all adjustment factors included in the NDS for dowel-type fasteners. The design of connection with steel side plate must comply with Section 11.2.3 of the NDS.

• Timber element specific gravity is considered as G = 0.42.

• Connections with multiple screws must be designed in accordance with the corresponding Sections of the NDS and ESR-4645.

• Z : Force-to-grain angle in the shear plane is considered as 90°.

• HBS screws must be positioned in accordance with the minimum distances.

• Zm : Force-to-grain angle in the shear plane is considered as 0° for side member and as 90° for main member.

• In case of combined axial and shear forces, the designer shall refer to the Hankinson formula, as specified in section 12.4.1 of the NDS, to evaluate the load-bearing capacity.

• For the connectors inserted in the panel’s face, it has been considered the same grain direction as the layer in the shear plane. For the connectors inserted in the panel’s narrow edge, it has been considered the same grain direction as the layer in which the connector is installed. • For lateral design values the force-to-fastener angle is always considered 90°. • Typical fastener spacings are declared considering a generic load condition; spacings should be verified and defined according to the real load conditions.

CLT | WALL-TO-WALL | FLOOR-TO-WALL • The main grain direction of the CLT wall panel is always considered as vertical. • The main grain direction of the CLT floor panel is considered both parallel and perpendicular to the wall plane. • The threaded part of the screw has been always considered inserted in the central layer of the CLT panel. • The withdrawal capacity has been considered as the minimum between thread withdrawal, head-pull through and tensile strenght of the screw. • According to NDS, an end grain coefficient Ceg=0.67 is considered for the lateral resistance calculation due to fastener in narrow edge of CLT.

SPLINE JOINT

Where: - Wref is the reference withdrawal design value for screws installed at an angle of 90° to the grain, as shown in the table on the left; - kα factor is calculated as:

kα =

• Z s : Force-to-grain angle in the shear plane is considered as 90° for side member and as 0° for main member.

CLT | FLOOR-TO-WOOD BEAM

• The steel side member must have a minimum tensile strength equal to 58 ksi (400 MPa) and comply with the minimum requirements of ASTM A36.

γM

• Z : Force-to-grain angle in the shear plane is considered as 0°.

35˚ < α ≤ 90˚

1 1.2·cos2(α)+sin2(α)

0˚ ≤ α ≤ 35˚

0.3+0.7·α 45

HALF LAP • The main grain direction of the CLT floor panel is considered both parallel and perpendicular to the machining’s direction. • The width of half-lap machining on CLT panel must comply with the minimum distance requirements. • The proposed screw’s lenghth does not exceed the total thickness of the connection.

• At least four screws must be used in a connection with screws installed in the wood member with an angle between the grain direction and screw axis α ≤ 15°.

BUTT JOINT

• The reference withdrawal design values must be inferior to ftens of the screw.

• The screw is considered inserted with an angle of 45° between the screw’s axis and CLT plane face.

REFERENCE HEAD PULL-THROUGH DESIGN VALUES

• According to NDS, an end grain coefficient Ceg=0.67 is considered for the lateral resistance calculation due to fastener in narrow edge of CLT.

While designing a connection the head pull-through values must be compared with the tensile resistance of the screw and, if necessary, thread withdrawal. The lower value is the governing one.

50 | HBS | TIMBER

• The axis of the connector on the shear plane is considered to run through the central layer of the panel.

INSTALLATION SUGGESTIONS SCREWING USING CATCH

Place the bit inside the CATCH screwing device and fasten it to the correct depth depending on the chosen connector.

CATCH is suitable with long connectors where the insert would otherwise tend to come out of the screw head space.

Useful in case of screwing in corners, which usually do not allow exerting a great screwing force.

PARTIALLY THREADED SCREWS vs FULLY THREADED SCREW

Compressible elements are interposed between two timber beams and a screw is screwed centrally to evaluate its effect on the connection.

The partial thread screw (e.g. HBS) allows the joint to be closed. The threaded portion, inserted all the way inside the second element, allows the first element to slide on the smooth shank.

The fully threaded screw (e.g. VGZ) transfers the force by exploiting its axial strength and penetrates inside the timber elements without moving.

Install the screw (e.g. HBS).

Alternatively, specific screws for hardwood applications (e.g. HBSH) can be used, which can be inserted without the aid of pre-drill hole

APPLICATION ON HARDWOODS

Pre-drill a hole of the required diameter (dV,H) and length equal to the chosen connector size using the SNAIL tip.

Ø0.24 inch HBS COIL APPLICATION The adapter plates for use of 0.16, 0.18, and 0.20 inch diameter HBS COIL screws are already supplied with the respective screwdriver loaders. To use HBS COIL screws with a diameter of 0.24 inch, the adapter plates supplied must be replaced with the adapter plate HZB6PLATE. For HBS COIL screws diameter 0.24 inch it is also necessary to use the appropriate TX30 bit (code HH14001469). We recommend using the extension HH14411591 for an easier installation of the screws on horizontal planes.

GENERAL PRINCIPLES • Tabulated values comply with NATIONAL DESIGN SPECIFICATION FOR WOOD CONSTRUCTION in accordance with ESR-4645. • To determine allowable loads for use with ASD, design loads for use with LRFD or both, tabulated values must be multiplied by all adjustment factors included in the NDS for dowel-type fasteners. • As part of the connection design, the structural wood members, the steel plates must be sized and verified in accordance with the corresponding Section of the NDS and must be done separately by the designer. • Connections with multiple screws must be designed in accordance with the corresponding Sections of the NDS and ESR-4645. • HBS screws must be positioned in accordance with the minimum distances.

• Designed connections must respect all requirements on general principles and minimum distances. • Calculations comply with the NDS in accordance with ESR 4645. • Tabulated values, that are referred to a single fastener, are valid for Allowable Stress Design (ASD) considering a standard loading (CD = 1.0). • Timber element specific gravity is considered as G = 0.42. • Z : Force-to-grain angle in the shear plane is considered as 0°. • Z : Force-to-grain angle in the shear plane is considered as 90°. • Zm : Force-to-grain angle in the shear plane is considered as 0° for side member and as 90° for main member. • Z s : Force-to-grain angle in the shear plane is considered as 90° for side member and as 0° for main member. • For the connectors inserted in the panel’s face, it has been considered the same grain direction as the layer in the shear plane. For the connectors inserted in the panel’s narrow edge, it has been considered the same grain direction as the layer in which the connector is installed. • For lateral design values the force-to-fastener angle is always considered 90°. • Resistance values are calculated considering one single screw.

CLT | FLOOR-TO-WOOD BEAM

STEEL-TO-WOOD • The steel side member must have a minimum tensile strength equal to 58 ksi (400 MPa) and comply with the minimum requirements of ASTM A36. • The wood main member thickness must be greater than the screw length minus the thickness of the steel side member. • In case of steel-to-wood connection with a thick plate, it is necessary to assess the effects of wood deformations and install the connectors according to the assembly instructions.

GENERAL NOTES

Wα = Wref ∙ kα ∙ Leff

HALF LAP

Where:

• The main grain direction of the CLT floor panel is considered both parallel and perpendicular to the machining’s direction. • The width of half-lap machining on CLT panel must comply with the minimum distance requirements. • The proposed screw’s length does not exceed the total thickness of the connection.

- Wref is the reference withdrawal design value for screws installed at an angle of 90° to the grain, as shown in the table on the left; - kα factor is calculated as:

kα =

35˚ < α ≤ 90˚

1 1.2·cos2(α)+sin2(α)

0˚ ≤ α ≤ 35˚

0.3+0.7·α 45

- α is the angle between the grain direction and screw axis. Tabulated values at page 44 are valid for Leff equal to the screw thread length b minus the tip length Lt and kα = 1 for α=90°, kα = 0.91 for α= 45°, kα = 0.3 for α = 0°. • The minimum embedded thread length is 6 times the outer thread diameter for screws installed at 90° to the grain, unless otherwise noted. • The minimum embedded thread length for screws installed at an angle 0° ≤ α < 90° to the grain is 8 times the outer thread diameter, unless otherwise noted. • At least four screws must be used in a connection with screws installed in the wood member with an angle between the grain direction and screw axis α ≤ 15°. • The reference withdrawal design values must be inferior to ftens of the screw.

REFERENCE LATERAL DESIGN VALUES While designing a connection the head pull-through values must be compared with the tensile resistance of the screw and, if necessary, thread withdrawal. The lower value is the governing one.

STEEL-TO-WOOD | CLT FLOOR-TO-STEEL BEAM • Steel side member must be pre-drilled in accordance with the indications provided in this technical data sheet and installation instructions. • A dowel bearing strength of Fe = 87,000 psi is used in the yield limit equations for the steel side member, in accordance with the NDS. • The main grain direction of the CLT floor panel is considered both parallel and perpendicular to the beam direction. • The withdrawal capacity has been considered as the minimum between thread withdrawal and tensile strength of the screw.

STEEL-TO-WOOD | STEEL SIDE PLATE CLT CONNECTION • Steel side member must be pre-drilled according to the information reported in these tecnical datasheet and installation instructions. • Beam element can be considered both solid wood or glulam. • The proposed screw length does not exceed the total thickness of the connection. In the case of steel plates on both sides of the beam, the geometry of the connection must be designed to avoid collisions between screws inserted from opposite sides. • A dowel bearing strength of Fe = 87,000 psi is used in the yield limit equations for the steel side member, in accordance with the NDS.

STEEL-TO-WOOD | STEEL SIDE PLATE CLT CONNECTION • Steel side member must be pre-drilled according to the information reported in these tecnical datasheet and installation instructions. • A dowel bearing strength of F e = 87,000 psi is used in the yield limit equations for the steel side member, in accordance with the NDS. • The main grain direction of the CLT floor panel is considered both parallel and perpendicular to the beam direction. • The withdrawal capacity has been considered as the minimum between thread withdrawal and tensile strength of the screw.

RESEARCH & DEVELOPMENT

STRUCTURAL DESIGN AND ACOUSTICS

The mechanical behaviour of timber-to-timber shear connections with a resilient sound insulation profile in between was studied in depth, both in terms of strength and stiffness, through an extensive experimental campaign.

EXPERIMENTAL INVESTIGATION 1

ANALYTICAL CHARACTERISATION OF A GAP CONNECTION USING PREDICTIVE MODELS For the analytical evaluation of the mechanical parameters of the connection (strength and stiffness), models available in the literature were applied, which modify Johansen's basic theory.

APPLICATION OF THE MODEL TO CONNECTIONS WITH AN INTERPOSED RESILIENT PROFILE Over 50 configurations considered by varying numerous parameters. RESILIENT PROFILES

(*)Directly proportional to the % of air contained in the material.

According to the analytical model, the use of large thickness values (s > 1/4") leads to a progressive degradation of strength and stiffness regardless of the type of profile interposed. Mechanical stiffness, on the other hand, shows a more or less marked degradation trend depending on the different parameters investigated and their interconnection.

In conclusion, the mechanical behaviour of the investigated connections under monotonic and cyclic loading conditions is not particularly influenced by the presence of the monolithic XYLOFON and PIANO acoustic profiles.

The strength values, as a first approximation, can, in the case of profiles with a thickness not exceeding 1/4", always be traced back to the case of direct timber-to-timber connection, thus neglecting the presence of the acoustic profile.

NOTES • Values in blue are from Table 10 of ESR-4645 (REDUCED CONNECTION GEOMETRY REQUIREMENTS BASED ON TESTING); • The minimum spacing and distances comply with Table 8 of ESR-4645, where d refers to the nominal diameter of the screw;

• Wood member stresses must be checked in accordance with the corresponding Sections of the NDS; end distances, edge distances and fastener spacing may need to be increased accordingly.

NOTES and GENERAL PRINCIPLES on page 100.

TIMBER | TBS | 99

GENERAL PRINCIPLES

CONNECTIONS

• Tabulated values comply with NATIONAL DESIGN SPECIFICATION FOR WOOD CONSTRUCTION in accordance with ESR-4645.

GENERAL NOTES

• To determine allowable loads for use with ASD, design loads for use with LRFD or both, tabulated values must be multiplied by all adjustment factors included in the NDS for dowel-type fasteners.

• Designed connections must respect all requirements on general principles and minimum distances.

• As part of the connection design, the structural wood members, must be sized and verified in accordance with the corresponding Section of the NDS and must be done separately by the designer.

• Tabulated values, that are referred to a single fastener, are valid for Allowable Stress Design (ASD) considering a standard loading (CD = 1.0).

• Connections with multiple screws must be designed in accordance with the corresponding Sections of the NDS and ESR-4645. • TBS screws must be positioned in accordance with the minimum distances. • In case of combined axial and shear forces, the designer shall refer to the Hankinson formula, as specified in section 12.4.1 of the NDS, to evaluate the load-bearing capacity.

• Calculations comply with the NDS in accordance with ESR 4645.

• Timber element specific gravity is considered as G = 0.42. • Z : Force-to-grain angle in the shear plane is considered as 0°. • Z : Force-to-grain angle in the shear plane is considered as 90°. • Zm : Force-to-grain angle in the shear plane is considered as 0° for side member and as 90° for main member. • Z s : Force-to-grain angle in the shear plane is considered as 90° for side member and as 0° for main member. • For the connectors inserted in the panel’s face, it has been considered the same grain direction as the layer in the shear plane. For the connectors inserted in the panel’s narrow edge, it has been considered the same grain direction as the layer in which the connector is installed. • For lateral design values the force-to-fastener angle is always considered 90°. • Typical fastener spacings are declared considering a generic load condition; spacings should be verified and defined according to the real load conditions.

WOOD-TO-WOOD

• The threaded part of the screw has been always considered inserted in the central layer of the CLT panel.

• The wood main member thickness must be greater than the screw length minus the thickness of the wood side member.

• The withdrawal capacity has been considered as the minimum between thread withdrawal, head-pull through and tensile strength of the screw.

• The tabulated lateral design values are based on both wood members having the same specific gravity G.

• According to NDS, an end grain coefficient Ceg=0.67 is considered for the lateral resistance calculation due to fastener in narrow edge of CLT.

REFERENCE WITHDRAWAL DESIGN VALUES

CLT | FLOOR-TO-WOOD BEAM

• The reference withdrawal design values (Wref) expressed in pounds-force per inch of thread penetration into the main member for screws installed at an angle of 90° to the grain can be found in the ESR-4645.

• The main grain direction of the CLT floor panel is considered both parallel and perpendicular to the beam’s axis.

• The values for screws installed at an angle α to the grain are determined by multiplying the reference withdrawal design values with the effective thread penetration Leff of the screw in the wood member and with the factor kα: Wα = Wref ∙ kα ∙ Leff - Wref is the reference withdrawal design value for screws installed at an angle of 90° to the grain, as shown in the table on the left; - kα factor is calculated as:

kα =

- α is the angle between the grain direction and screw axis. Tabulated values at page 95 are valid for L eff equal to the screw thread length b minus the tip length Lt and kα = 1 for α=90°, kα = 0.91 for α= 45°, kα = 0.3 for α = 0°. • The minimum embedded thread length is 6 times the outer thread diameter for screws installed at 90° to the grain, unless otherwise noted. • The minimum embedded thread length for screws installed at an angle 0° ≤ α < 90° to the grain is 8 times the outer thread diameter, unless otherwise noted.

• Beam element can be considered both solid wood or glulam. • Double lumber is considered as two coupled element of 2 inches thick. • The width of the beams must comply with the minimum distance requirements. • The proposed screw’s length does not exceed the total thickness of the connection. In configurations with no declared value (-) the fastener exceeds the main member depth.

SPLINE JOINT • Spline thickness is considered to be thinner than the top CLT layer. • For Root Diameter d 2 >0.25 inch, the bearing strength of the spline is conservatively considered as 3350 psi according to NDS. • The main grain direction of the CLT floor panel is considered both parallel and perpendicular to the spline’s direction. • The width of the spline and consequent machining on CLT panel must comply with the minimum distance requirements.

• At least four screws must be used in a connection with screws installed in the wood member with an angle between the grain direction and screw axis α ≤ 15°.

HALF LAP

• The reference withdrawal design values must be inferior to ftens of the screw.

• The main grain direction of the CLT floor panel is considered both parallel and perpendicular to the machining’s direction.

REFERENCE HEAD PULL-THROUGH DESIGN VALUES

• The width of half-lap machining on CLT panel must comply with the minimum distance requirements.

While designing a connection the head pull-through values must be compared with the tensile resistance of the screw and, if necessary, thread withdrawal. The lower value is the governing one.

TIMBER | TBS MAX | 111

GENERAL PRINCIPLES

CONNECTIONS

• Tabulated values comply with NATIONAL DESIGN SPECIFICATION FOR WOOD CONSTRUCTION in accordance with ESR-4645.

GENERAL NOTES

• To determine allowable loads for use with ASD, design loads for use with LRFD or both, tabulated values must be multiplied by all adjustment factors included in the NDS for dowel-type fasteners.

• Designed connections must respect all requirements on general principles and minimum distances.

• Tabulated values, that are referred to a single fastener, are valid for Allowable Stress Design (ASD) considering a standard loading (CD = 1.0).

• Connections with multiple screws must be designed in accordance with the corresponding Sections of the NDS and ESR-4645. • TBS MAX screws must be positioned in accordance with the minimum distances. • In case of combined axial and shear forces, the designer shall refer to the Hankinson formula, as specified in section 12.4.1 of the NDS, to evaluate the load-bearing capacity.

• Calculations comply with the NDS in accordance with ESR 4645.

• Timber element specific gravity is considered as G = 0.42. • Z : Force-to-grain angle in the shear plane is considered as 0°. • Z : Force-to-grain angle in the shear plane is considered as 90°. • Zm : Force-to-grain angle in the shear plane is considered as 0° for side member and as 90° for main member. • Z s : Force-to-grain angle in the shear plane is considered as 90° for side member and as 0° for main member. • For the connectors inserted in the panel's face, it has been considered the same grain direction as the layer in the shear plane. For the connectors inserted in the panel's narrow edge, it has been considered the same grain direction as the layer in which the connector is installed. • For lateral design values the force-to-fastener angle is always considered 90°. • Typical fastener spacings are declared considering a generic load condition; spacings should be verified and defined according to the real load conditions.

CLT | FLOOR-TO-WOOD BEAM REFERENCE WITHDRAWAL DESIGN VALUES • The reference withdrawal design values (Wref) expressed in pounds-force per inch of thread penetration into the main member for screws installed at an angle of 90° to the grain can be found in the ESR-4645. • The values for screws installed at an angle α to the grain are determined by multiplying the reference withdrawal design values with the effective thread penetration Leff of the screw in the wood member and with the factor kα:

γM

Wα = Wref ∙ kα ∙ Leff

• According to NDS, an end grain coefficient Ceg=0.67 is considered for the lateral resistance calculation due to fastener in narrow edge of CLT.

Where:

• Beam element can be considered both solid wood or glulam.

- Wref is the reference withdrawal design value for screws installed at an angle of 90° to the grain, as shown in the table on the left; - kα factor is calculated as:

• Double lumber is considered as two coupled element of 2 inches thick.

kα =

35˚ < α ≤ 90˚

1 1.2·cos2(α)+sin2(α)

0˚ ≤ α ≤ 35˚

0.3+0.7·α 45

- α is the angle between the grain direction and screw axis. Tabulated values at page 108 are valid for Leff equal to the screw thread length b minus the tip length Lt and kα = 1 for α=90°, kα = 0.91 for α= 45°, kα = 0.3 for α = 0°.

• The width of the beams must comply with the minimum distance requirements. • The proposed screw’s length does not exceed the total thickness of the connection. In configurations with no declared value (-) the fastener exceeds the main member depth.

• The minimum embedded thread length is 6 times the outer thread diameter for screws installed at 90° to the grain, unless otherwise noted.

• The main grain direction of the CLT floor panel is considered both parallel and perpendicular to the spline’s direction.

• The minimum embedded thread length for screws installed at an angle 0° ≤ α < 90° to the grain is 8 times the outer thread diameter, unless otherwise noted.

• The width of the spline and consequent machining on CLT panel must comply with the minimum distance requirements.

• At least four screws must be used in a connection with screws installed in the wood member with an angle between the grain direction and screw axis α ≤ 15°.

HALF LAP

• The reference withdrawal design values must be inferior to ftens of the screw.

REFERENCE HEAD PULL-THROUGH DESIGN VALUES While designing a connection the head pull-through values must be compared with the tensile resistance of the screw and, if necessary, thread withdrawal. The lower value is the governing one.

A breakthrough in fast, reliable, glue-free timber connections The SHARP METAL hooked plate revolutionises timber-to-timber connections with a simple but incredibly effective system. The multitude of small hooks distributed over the two surfaces of the plate allows for a secure joint that can be easily removed when necessary. Ideal for ribbed or formwork floors: thanks to the SHARP METAL hooks and TBS MAX tightening, there is no need for glues, adhesives or presses.

FLAT FLANGE HEAD SCREW FLAT FLANGE HEAD The flange head ensures excellent tightening capacity of the joint; the flat shape allows a joint without additional thickness on the wooden surface, thus enabling the fixing of plates on the same element without interference.

SHORT THREAD The short, fixed-length thread at 1 5/16" (34 mm) is optimised for fastening multi-layer elements (Multi-ply) for lightweight frame construction.

BLACK E-COATING Coated with black E-coating for easy recognition on site and increased corrosion resistance.

3 THORNS TIP TBSF is easily installed without pre-drilling hole. More screws can be used in less space and larger screws in smaller elements.

GENERAL PRINCIPLES

CONNECTIONS

• Tabulated values comply with NATIONAL DESIGN SPECIFICATION FOR WOOD CONSTRUCTION in accordance with ESR-4645.

GENERAL NOTES

• To determine allowable loads for use with ASD, design loads for use with LRFD or both, tabulated values must be multiplied by all adjustment factors included in the NDS for dowel-type fasteners.

• Designed connections must respect all requirements on general principles and minimum distances.

• As part of the connection design, the structural wood members, must be sized and verified in accordance with the corresponding Section of the NDS and must be done separately by the designer.

• Tabulated values, that are referred to a single fastener, are valid for Allowable Stress Design (ASD) considering a standard loading (CD = 1.0).

• Connections with multiple screws must be designed in accordance with the corresponding Sections of the NDS and ESR-4645. • TBS FRAME screws must be positioned in accordance with the minimum distances. • In case of combined axial and shear forces, the designer shall refer to the Hankinson formula, as specified in section 12.4.1 of the NDS, to evaluate the load-bearing capacity.

• Calculations comply with the NDS in accordance with ESR 4645.

• Timber element specific gravity is considered as G = 0.42. • Z : Force-to-grain angle in the shear plane is considered as 0°. • Z : Force-to-grain angle in the shear plane is considered as 90°. • Zm : Force-to-grain angle in the shear plane is considered as 0° for side member and as 90° for main member. • Z s : Force-to-grain angle in the shear plane is considered as 90° for side member and as 0° for main member. • For the connectors inserted in the panel's face, it has been considered the same grain direction as the layer in the shear plane. For the connectors inserted in the panel's narrow edge, it has been considered the same grain direction as the layer in which the connector is installed. • For lateral design values the force-to-fastener angle is always considered 90°. • Typical fastener spacings are declared considering a generic load condition; spacings should be verified and defined according to the real load conditions.

γM

Wα = Wref ∙ kα ∙ Leff

• According to NDS, an end grain coefficient Ceg=0.67 is considered for the lateral resistance calculation due to fastener in narrow edge of CLT.

Where:

• Beam element can be considered both solid wood or glulam.

- Wref is the reference withdrawal design value for screws installed at an angle of 90° to the grain, as shown in the table on the left; - kα factor is calculated as:

• Double lumber is considered as two coupled element of 2 inches thick.

kα =

35˚ < α ≤ 90˚

1 1.2·cos2(α)+sin2(α)

0˚ ≤ α ≤ 35˚

0.3+0.7·α 45

- α is the angle between the grain direction and screw axis. Tabulated values at page 118 are valid for L eff equal to the screw thread length b minus the tip length Lt and kα = 1 for α=90°, kα = 0.91 for α= 45°, kα = 0.3 for α = 0°.

• The minimum embedded thread length is 6 times the outer thread diameter for screws installed at 90° to the grain, unless otherwise noted.

• The main grain direction of the CLT floor panel is considered both parallel and perpendicular to the spline’s direction.

• The minimum embedded thread length for screws installed at an angle 0° ≤ α < 90° to the grain is 8 times the outer thread diameter, unless otherwise noted.

• The width of the spline and consequent machining on CLT panel must comply with the minimum distance requirements.

• At least four screws must be used in a connection with screws installed in the wood member with an angle between the grain direction and screw axis α ≤ 15°.

HALF LAP

• The reference withdrawal design values must be inferior to ftens of the screw.

NOTES and GENERAL PRINCIPLES on page 133.

132 | TBS EVO | TIMBER

GENERAL PRINCIPLES

CONNECTIONS

• Tabulated values comply with NATIONAL DESIGN SPECIFICATION FOR WOOD CONSTRUCTION in accordance with ESR-4645.

GENERAL NOTES

• To determine allowable loads for use with ASD, design loads for use with LRFD or both, tabulated values must be multiplied by all adjustment factors included in the NDS for dowel-type fasteners.

• Designed connections must respect all requirements on general principles and minimum distances.

• Tabulated values, that are referred to a single fastener, are valid for Allowable Stress Design (ASD) considering a standard loading (CD = 1.0).

• Connections with multiple screws must be designed in accordance with the corresponding Sections of the NDS and ESR-4645. • TBS EVO screws must be positioned in accordance with the minimum distances. • In case of combined axial and shear forces, the designer shall refer to the Hankinson formula, as specified in section 12.4.1 of the NDS, to evaluate the load-bearing capacity.

• Calculations comply with the NDS in accordance with ESR 4645.

• Timber element specific gravity is considered as G = 0.42. • Z : Force-to-grain angle in the shear plane is considered as 0°. • Z : Force-to-grain angle in the shear plane is considered as 90°. • Zm : Force-to-grain angle in the shear plane is considered as 0° for side member and as 90° for main member. • Z s : Force-to-grain angle in the shear plane is considered as 90° for side member and as 0° for main member. • For the connectors inserted in the panel's face, it has been considered the same grain direction as the layer in the shear plane. For the connectors inserted in the panel's narrow edge, it has been considered the same grain direction as the layer in which the connector is installed. • For lateral design values the force-to-fastener angle is always considered 90°. • Typical fastener spacings are declared considering a generic load condition; spacings should be verified and defined according to the real load conditions.

γM

Wα = Wref ∙ kα ∙ Leff

• According to NDS, an end grain coefficient Ceg=0.67 is considered for the lateral resistance calculation due to fastener in narrow edge of CLT.

Where:

• Beam element can be considered both solid wood or glulam.

- Wref is the reference withdrawal design value for screws installed at an angle of 90° to the grain, as shown in the table on the left; - kα factor is calculated as:

• Double lumber is considered as two coupled element of 2 inches thick.

kα =

35˚ < α ≤ 90˚

1 1.2·cos2(α)+sin2(α)

0˚ ≤ α ≤ 35˚

0.3+0.7·α 45

- α is the angle between the grain direction and screw axis. Tabulated values at page 128 are valid for Leff equal to the screw thread length b minus the tip length Lt and kα = 1 for α=90°, kα = 0.91 for α= 45°, kα = 0.3 for α = 0°.

• The minimum embedded thread length is 6 times the outer thread diameter for screws installed at 90° to the grain, unless otherwise noted.

• The main grain direction of the CLT floor panel is considered both parallel and perpendicular to the spline’s direction.

• The minimum embedded thread length for screws installed at an angle 0° ≤ α < 90° to the grain is 8 times the outer thread diameter, unless otherwise noted.

• The width of the spline and consequent machining on CLT panel must comply with the minimum distance requirements.

• At least four screws must be used in a connection with screws installed in the wood member with an angle between the grain direction and screw axis α ≤ 15°.

HALF LAP

• The reference withdrawal design values must be inferior to ftens of the screw.

AXIALLY LOADED CONNECTORS FULLY THREADED SCREWS STRENGTH The strength is proportional to the effective thread length within the timber element. The connectors guarantee high performances even with small diameters. The stresses are distributed, as of tangential stresses, along the entire wood surface affected by the screw thread. For the verification of a connection with axially stressed connectors, it will be necessary to evaluate the limiting strength, depending on the acting load. The strength of the full thread connector is related to its mechanical performance and the type of wood material in which it is applied.

The graph refers to shear tests to control displacement for HBS screws under lateral stress (shear) and crossed VGZ axially loaded screws.

PARTIAL THREAD SCREWS The strength is proportional to the diameter and is related to the bearing stress of the timber and the yielding of the screw. The partial thread is mainly used to transfer shear forces that stress the screw perpendicular to its axis. If the screw is under tensile stress, the pull-through strength of the head must be taken into account, which is often a constraint compared to the withdrawal resistance of the threaded part and compared to the tensile strength on the steel side.

140 | AXIALLY LOADED CONNECTORS | TIMBER

s - slip [in]

APPLICATIONS To optimise the performance of full thread or double thread connectors, it is essential to use them in such a way that they are subjected to axial stress. The load is distributed parallel to the axis of the connectors along the effective thread portion. They are used to transfer shear and sliding stresses, for structural reinforcement or for fixing continuous insulation.

STRUCTURAL REINFORCEMENT Wood is an anisotropic material. Therefore, it has different mechanical characteristics depending on the direction of the grain and the stress. It provides less resistance and stiffness for stresses orthogonal to the grain, but can be reinforced with full thread connectors (VGS, VGZ or RTR).

FASTENING FOR CONTINUOUS INSULATION Installation of a continuous layer of insulation guarantees excellent energy performance, limiting thermal bridges. Efficiency is bound to the use of appropriate fastening systems (ex. DGZ), suitably designed.

SLIDING OF INSULATION AND ROOFING PROBLEM The connectors for fixing insulation prevent the package from sliding due to the load component parallel to the pitch, resulting in damage to the roof system and loss of insulating power.

If insulation does not have sufficient compressive strength, the connectors with double threads effectively transfer the loads and prevent crushing with consequent loss of insulating power of the assembly.

ROOFING AND FAÇADE APPLICATIONS COVER

FAÇADE

SOFT INSULATION Low compression resistance σ(10%) < 7 psi

HARD INSULATION High compression resistance σ(10%) ≥ 7 psi

SOFT OR HARD CONTINUOUS INSULATION

A C

±N

The continuous insulation does not support the load component perpendicular to the layer (N).

The continuous insulation supports the load component perpendicular to the layer (N);

Fasteners must withstand both wind actions (±N) and transfer vertical forces (F).

LEGEND: A. Tension-stressed screw. B. Compression-stressed screw. C. Additional screw for suction pressure. NOTE: Adequate batten thickness makes it possible to optimise the number of fastenings.

FULL THREADED SCREW WITH CYLINDRICAL HEAD 3 THORNS TIP Thanks to the 3 THORNS tip, minimum installation distances are reduced. More screws can be used in less space and larger screws in smaller elements. Costs and time for project implementation are reduced.

STRUCTURAL APPLICATIONS Approved for structural applications subject to stresses in any direction vs the grain (0° - 90°). Cyclical SEISMIC-REV tests according to EN 12512.

CYLINDRICAL HEAD It allows the screw to penetrate and pass through the surface of the wood substrate. Ideal for concealed joints, timber couplings and structural reinforcements. It is the right choice to ensure strength in fire conditions.

TIMBER FRAME Also ideal for joining small timber elements such as the crossbeams and uprights of light frame structures.

INSTALLATION SUGGESTIONS TIMBER-TO-TIMBER JOINT WITH CROSSED CONNECTORS TIGHTENING THE JOINT

For correct installation of the joint, we recommend tightening the elements before inserting the connectors.

Insert a partially threaded screw (e.g. HBS680) to bring the elements closer together.

The HBS screw eliminated the initial gap between the elements. After positioning the VGZ connectors, it can be removed.

After tightening about one third of the screw, remove the JIGVGZ45 template and continue with the installation.

Repeat the procedure to install the inserted screw from the main beam to the secondary beam.

INSERTION OF CONNECTORS

To ensure the correct positioning and inclination of the VGZ screws, we recommend using the JIGVGZ45 template.

JOINT BETWEEN CLT PANELS WITH CONNECTORS INCLINED IN BOTH DIRECTIONS (45°-45°)

To ensure the correct positioning and inclination of the VGZ screws, we recommend using the JIGVGZ45 template positioned at 45° to the panel head.

After tightening about one third of the screw, remove the JIGVGZ45 template and continue with the installation.

Repeat the procedure to install the screw in the adjoining panel and continue this alternating sequence according to the distances provided in the design.

GENERAL PRINCIPLES

CONNECTIONS

• Tabulated values comply with NATIONAL DESIGN SPECIFICATION FOR WOOD CONSTRUCTION in accordance with ESR-4645.

GENERAL NOTES

• To determine allowable loads for use with ASD, design loads for use with LRFD or both, tabulated values must be multiplied by all adjustment factors included in the NDS for dowel-type fasteners.

• Designed connections must respect all requirements on general principles and minimum distances.

• Tabulated values, that are referred to a single fastener, are valid for Allowable Stress Design (ASD) considering a standard loading (CD = 1.0).

• Connections with multiple screws must be designed in accordance with the corresponding Sections of the NDS and ESR-4645. • VGZ screws must be installed and used in dry in-service conditions in accordance with the NDS (wet service factor for connection CM is 1.0). • VGZ screws must be positioned in accordance with the minimum distances. • In the case of combined axial and shear forces on a screw, for the determination of the load-bearing capacity refer to the Hankinson formula found in the NDS section 12.4.1.

REFERENCE LATERAL DESIGN VALUES

• Calculations comply with the NDS in accordance with ESR 4645.

• Timber element specific gravity is considered as G = 0.42, unless otherwise noted. • Z : Force-to-grain angle in the shear plane is considered as 0°. • Z : Force-to-grain angle in the shear plane is considered as 90°. • Zm : Force-to-grain angle in the shear plane is considered as 0° for side member and as 90° for main member. • Rv: withrawal resistance of the screws projected on the shear force axis. • For the connectors inserted in the panel’s face, it has been considered the same grain direction as the layer in the shear plane. For the connectors inserted in the panel’s narrow edge, it has been considered the same grain direction as the layer in which the connector is installed.

• Tabulated values are determined from the yield model equations in the corresponding Section of the NDS. • Unless otherwise noted, the screw is intended to be inserted half in the main member and half in the side member.

• For lateral design values the force-to-fastener angle is always considered 90°.

• The screw penetration into the main member is minimum 6 times the outer thread diameter unless otherwise noted.

• The main grain direction of the CLT floor panel is considered both parallel and perpendicular to the beam's axis or wall plane.

• The reference lateral design values may be determined for other connection configurations in accordance with the corresponding Section of NDS and ESR-4645.

• The main grain direction of the CLT wall panel is always considered as vertical.

• The reference lateral design values are calculated for screws inserted without pre-drilling hole. In the case of screws inserted with pre-drilling hole, greater resistance values can be obtained.

• According to NDS, an end grain coefficient Ceg=0.67 is considered for the lateral resistance calculation due to fastener in narrow edge of CLT (FLOORTO-WALL).

WOOD-TO-WOOD

• Beam element can be considered both solid wood or glulam.

• The wood main member thickness must be greater than the screw length minus the thickness of the wood side member.

• The width of the beams must comply with the minimum distance requirements.

• The tabulated lateral design values are based on both wood members having the same specific gravity G.

REFERENCE WITHDRAWAL DESIGN VALUES

FLOOR-TO-BEAM | FLOOR-TO-WALL

• The threaded part of the screw has been always considered inserted in the central layer of the CLT panel.

• The proposed screw's length does not exceed the total thickness of the connection. • The CLT side Rv resistance is calculated taking into account a screw-tograin angle as the lowest between the involved layers. In this case the considered angle is 45°.

BUTT JOINT

• Force-to-fastener angle is considered to be 60°. The geometry of the joint requires that the connectors be inserted at an angle of 45° with respect to the face of the CLT panel, and at an angle of 45° with respect to the shear plane between the two panels.

Wα = Wref ∙ kα ∙ Leff

γM

Where:

• An end grain coefficient Ceg=0.67 is considered for the withrawal resistance calculation due to fastener in narrow edge of CLT.

- Wref is the reference withdrawal design value for screws installed at an angle of 90° to the grain, as shown in the table on the left; - kα factor is calculated as:

• Reported values represent the shear resistance of the connection along the shear plane for a single fastener.

kα =

35˚ < α ≤ 90˚

1 1.2·cos (α)+sin2(α)

0˚ ≤ α ≤ 35˚

0.3+0.7·α 45

- α is the angle between the grain direction and screw axis. Tabulated values at page 151 are valid for Leff equal to the screw thread length b minus the tip length Lt and kα = 1 for α=90°, kα = 0.91 for α= 45°, kα = 0.3 for α = 0°. • The minimum embedded thread length is 6 times the outer thread diameter for screws installed at 90° to the grain, unless otherwise noted. • The minimum embedded thread length for screws installed at an angle 0° ≤ α < 90° to the grain is 8 times the outer thread diameter, unless otherwise noted. • At least four screws must be used in a connection with screws installed in the wood member with an angle between the grain direction and screw axis α ≤ 15°. • The reference withdrawal design values must be inferior to ftens of the screw.

REFERENCE WITHDRAWAL DESIGN VALUES

• The proposed screw's length does not exceed the total thickness of the connection. • The use of the JIG VGZ 45 template is recommended to ensure precise installation of the connectors in this application.

HALF LAP • The main grain direction of the CLT floor panel is considered both parallel and perpendicular to the machining's direction. • Force-to-fastener angle is considered as 45°. The screw are considered inserted at an angle of 45° with respect to the face of the CLT panel in the machining's direction. In this direction the the screw is intended to work in withrawal. In the opposite direction the screws are intended to work in shear. • The width of half-lap machining on CLT panel must comply with the minimum distance requirements. • The proposed screw's length does not exceed the total thickness of the connection. • Rv resistance is calculated by taking into account the screw-to-grain angle as the lowest among the involved layers. In this case, the angle considered is 45°.

For fully-threaded screws the head pull-through resistanche is not relevant for the connection resistance, thread withdrawalis governing. these values must be compared with the tensile resistance of the screw; the lower value is the governing one.

SLIDING RESISTANCE • Unless otherwise noted, the screws is inend to be inserted half in the main member and half in the side member. • The 45° inclined screw is intended to work in withrawal and the resulting resistance of the connection is given by the projection of the withrawal resistance (along screw axis) onto the shear plane. • The design values must be inferior to ftens of the screw projected onto the shear plane.
