Self-tapping screws create their own "female thread" during installation—when screwing into ready-made holes—without creating any chips. This creates an optimum screw connection in steel, die cast metal, aluminium, brass and copper with minimal installation costs.
Guidelines for core hole diameter
In copper and copper alloy (E-CU F30 and CuZn F38); aluminium and aluminium alloys (Al 99.5 F13 and AlMn F10) and steel (St 12 and 37). In certain cases, ideal values can only be established in laboratory tests.
