Detent Pin

A detent pin is a quick-release fastener with a spring-loaded ball or pin that locks it in place. It allows fast manual removal and reinsertion without tools.

A detent pin holds parts in place and releases quickly by hand. It often fits a drilled hole or a mating part with a matching bore. The pin can be matched with a lanyard or a retaining feature to keep it close to the joint.

This kind of pin is often made in stainless steel. That gives good corrosion resistance for outdoor or damp 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 material test certificate. On receipt, check the pin diameter, the spring action and the surface for damage.
