Locking Pin

A locking pin is a removable fastener that holds two parts in place and can be taken out again without tools. It often has a spring or detent to keep it seated.

A locking pin holds parts in place and resists loosening from vibration. It often fits through aligned holes and can be secured with a clip or split pin. Match it to the hole diameter and the load it carries.

Hot dip galvanising gives a thick zinc coating for outdoor or damp service. Plain finish is bare metal with no added coating. PTFE coating lowers friction and helps resist sticking.

This kind of pin is often made in stainless steel 304 or 316 for corrosion resistance, in steel for higher strength, or in brass for non-magnetic or decorative use.

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 pin diameter, length and finish, and look for cracks or burrs.
