• We recommend pre-drilling into any hardwood timbers to prevent splitting and cupping. • We recommend to use T316 screws for some hardwoods which contain high tannins to minimise the risk of black staining around the screws on the timber. If staining occurs use of oxalic acid may help to reduce or remove it. • All data based on average loads, pull-out values will vary depending on the timber used.
