Wing Screw

A wing screw is a threaded fastener with a head that can be turned by hand. It is used where frequent adjustment is needed without tools.

A wing screw passes through a part and threads into a tapped hole or a nut. Its head is turned by hand for quick tightening and release. It suits covers, panels and fittings that are adjusted often.

This kind of screw is often made in stainless steel 304, stainless steel 316, or steel. Stainless steel grades resist rust in damp or outdoor conditions. Steel grades are common for general use.

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 if you need proof of material or dimensions. On receipt, check the thread with a gauge. Turn the screw by hand to check the wings and thread.
