SCREWBOLTS An anchor bolt with an external thread which cuts its own thread into the base material after a pilot hole has been drilled. The Screwbolt can withstand a load as soon as the thread engages in the base material. Screwbolts are completely removable, virtually expansion free, making them ideal for close to edge distance fixing. Ideal for most anchor fixing requirements into concrete.
