Hammer Drive Pins

Hammer drive pins are cold-formed pins with helical knurls and are used to replace screws where the need to remove the pin is unlikely. Hammer drive pins are designed for installation by hammer or press.
Hammer drive pins are made in low carbon steel and the knurl has to cut its way into the walls of the hold. They are available as in either a round headed or flat headed version and designed for use with unhardened materials such as mild steel, aluminium, brass or plastics.
