Spring Nut

A spring nut is a nut with a spring clip or spring steel body that holds position or applies tension. It is used where a part must stay located during assembly.

A spring nut clips onto a panel edge or into a channel and holds itself in place. It takes a bolt or screw of the same thread, often without a separate washer. It is used where access for a nut and spanner is limited.

This kind of nut is often made in stainless steel. A2 and A4 grades are common where corrosion resistance matters.

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 steel grade. On receipt, check the spring action and the thread.
