Wing Nut

A wing nut is a nut with two flat wings that can be turned by hand. It is used where the joint is adjusted often and tools are not wanted.

A wing nut tightens by hand where frequent adjustment is expected. It suits a mating bolt or stud of the same thread and can be backed with a washer.

This kind of nut is usually made in carbon steel, stainless steel or brass. Carbon steel suits general work, stainless steel suits damp or outdoor conditions and brass suits light duty and electrical work.

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 wing shape, the thread fit and the surface for sharp edges.
