Construction or structural wood screws with an internal hexalobular, with a plate head. In addition to the classic white zinc chromate, the screws are also treated with slip lacquer for more convenient screwing without pre-drilling. There is also a cutter in the middle of the shaft to significantly facilitate the drilling of long screws. Special milled tips allow easier penetration even into very hard wood.
