Construction or structural wood screws with internal hexalobular, with countersunk head. In addition to the classic yellow 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.
