Thread-rolling screws create their own "female thread" during installation - when screwing into ready-made holes - without creating any chips. This creates an optimal screw connection in steel, high-pressure 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.
