ISO 15481 Self-Tapping Screw with Round Head and Drill Point Phillips-KS

The ISO 15481 self-tapping screw with round head and drill point Phillips-KS is designed for working with metal. The fastener’s head has a cross recess for a shaped screwdriver or power screwdriver bit. The drill-shaped point and fine thread pitch allow quick fastening of thin metal sheets to profile framing.

Using ISO 15481 self-tapping screws eliminates the need to pre-drill holes, which reduces work time and electricity costs. The raw material for this category of fasteners is plain steel or steel with a zinc-plated coating. The main application area is construction, including finishing and restoration work.
