A rivet nut, also known as a threaded insert or a blind rivet nut, is a mechanical fastener. It is a variation of the standard rivet. Because of their wide grip range tolerance, rivet nuts can be installed into a variety of material thicknesses. This one-piece, threaded, counter-bored tubular rivet can be anchored entirely from one side of the material in which it's installed. Rivet nuts are easy-to-install, reliable fasteners that can provide strong load-bearing threads into weak or thin gauge materials such as castings, housings, panels, tubes, and extrusions. But for individual use, you can install rivet nuts using easy-to-operate and lightweight hand tools or air/hydraulic setting tools.
