Snap Pin

A snap pin is a quick-release fastener with a spring wire or a bent wire loop that snaps into a hole or over a shaft. It holds parts together and can be removed by hand.

A snap pin locks quickly through a hole and releases by hand. It often has a spring leg that grips the hole edge. Match it to the hole diameter and the load it carries.

Snap pins are often made in spring steel or stainless steel. Spring steel gives good elasticity and can be plated for corrosion resistance. Stainless steel suits outdoor or wet conditions.

This is a general guide to checking this kind of part. It says nothing about any supplier's parts.

Ask for a certificate of conformance and a mill test certificate for the material. On receipt, check the wire diameter, overall shape and spring action, and look for cracks or weak spots.
