The screw is made of hardened steel with a surface treatment of CorrSeal for outdoor use. It's equipped with TX mount/bits. The screw has a patent head shape that minimizes splinters and gives a good finish result. For length 70mm and longer it has an extra milling thread direct after the ordinary thread that ease the mounting of longer and larger screws. Underneath the head, the screw has cutting mills that cut the wood fibers and recess the screw into the wood with a smooth surface without splinters. The head also works well in recessed connectors though it doesn't have protruding ribs. The screw fulfills the CE demands according to EN14592.
