Flat Head Hammer Drive Pins. Used to replace screws where the need to remove the pin is unlikely.

• Low Carbon Steel (Series HP210) - self-colour, not plated cold formed pin.
• Simple, low cost assembly for use in mild steel, aluminium, brass or plastics.
• Secure - unlike a machine screw, a drive stud does not depend on tightening torque to be retained in the assembly.
• Drive studs do not require lock washers to prevent back-out.
• Designed for standard metric hole sizes and installation by hammer or press. Cold formed pins with helical knurls.
