Rivet nut

Typical rivet nut

A rivet nut, also known as a blind rivet nut, blind nut, rivnut, threaded insert or nut-sert,[1] is a one-piece internally threaded and counterbored tubular rivet that can be anchored entirely from one side. There are two types: one is designed to form a bulge on the back side of the panel as a screw is tightened in its threads. The other is similarly drawn in using a screw, but is drawn into the sleeve instead of creating a bulge.[2][3]

History

The first rivet nut was created and named rivnut by BF Goodrich in the 1930s. It was first used to mount rubber de-icing boots to aircraft wings.[4]

Usage

In the field of aviation, rivnuts are often used to attach various items, such as static dischargers and inspection access covers, to the surface of an aircraft.
