Are you going to use wood with tannic acid in it? Then make sure you use our stainless steel screws Full thread 4.5 x 40 mm for Oak, Accoya, Red Cedar and Garapa wood. The special coating of this screw ensures that no black spots form in the wood, which can happen with a normal stainless steel screw, this is the effect of tannic acid with stainless steel. This screw is specially designed against tannic acid and is also stainless.

The head of the screw has a Torx 25 drive, use the Torx 20 bits from Wovar to tighten the screw properly. You don't have to worry about damaging the screw while screwing in, because the coating is self-healing. Under the head of the screw are milling ribs so that the screw will sink nicely into the wood. Pre-drilling is recommended and is easy with our 3.5 mm thick hardwood drill bit.
