Ball Lock Pin

A quick-release pin with a ball lock that holds the pin in place until a button is pressed. It allows fast fitting and removal without tools.

A ball lock pin passes through aligned holes to hold parts together and releases quickly. It is often used for temporary joints or quick changes. It can be matched with a lanyard or a retaining cable.

Ball lock pins are often made in stainless steel or zinc-plated steel. Stainless steel suits damp and outdoor use. Plated steel gives high strength at lower cost but needs the coating kept intact.

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 check the pin diameter, grip length and ball action against the order. On receipt, test the release action and look for burrs, play in the balls and damage to the coating.
