Countersunk head screw with cross slot DIN 7997

The DIN 7997 universal self-tapping screw is a truly versatile fastener due to its diverse applications, used for joining wood, chipboard, fiberboard, drywall, thin sheet metal, firmly fixing in dowels and other various types of assembly and installation. Self-tapping screws differ from conventional screws in terms of material quality, coating, wider and sharper threads, and an improved slot for a bit. The self-tapping screw's ability to be screwed in without preliminary drilling is due to its sharp end and 40-degree thread, which provides the screw with a reliable and strong connection even with a small torque.
