Wedge Nut

A wedge nut is a nut with a wedge shaped body that locks into a matching slot or channel. It is used where a nut must resist turning or pulling out.

A wedge nut locks or tensions a joint where a wedge action is needed. It often pairs with a matching wedge pin or bolt and is set with a hammer or spanner.

This kind of nut is usually made in carbon steel or stainless steel. Carbon steel suits general work and stainless steel suits damp or outdoor 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 if the material grade matters. On receipt, check the wedge angle, the thread form and the surface for cracks.
