The Forgefast Wafer Head Torx(r) Compatible Construction Screws are suitable for fixing into softwood or hardwood. They have a deep Torx(r) compatible insert that reduces cam-out, provides higher torque levels and a firmer drive. Its super sharp tip gives immediate bite from the very first turn. A patented self-drilling thread removes the need to pre-drill the timber and reduces the probability of splitting, even when screwing close to the edge. They have a hardened case and core to give exceptional strength. Protected by elementech 2000 surface treatment which provides corrosion resistance up to 30 times longer than some standard zinc coated screws. They are highly resistant to pull out, they can flex by up to 35, reducing likelihood of the screw shearing when used in flexible materials. CE approved for use in load-bearing timber construction.
