What is rivet nuts?

Rivet nuts, also known as threaded inserts, are a type of fastener used to create a permanent thread in thin materials. They are commonly used in sheet metal, tubing, and other thin-walled materials where it may not be possible to use a traditional nut and bolt.

Rivet nuts can be made of various materials, including aluminum, stainless steel, and brass. They come in a range of diameters and lengths to accommodate different applications.

There are different types of rivet nuts, including:

1. Blind rivet nuts: These are installed from one side of the material and provide a threaded hole on the opposite side.

2. Threaded inserts: These are installed from either side of the material and provide a threaded hole.

3. Swage threaded inserts: These are installed by collapsing the insert against the material using a tool.

Rivet nuts are typically installed using a special tool called a rivet nut setter or a threaded insert tool. The tool pulls the mandrel through the rivet nut, causing it to expand and grip the material. Once installed, the rivet nut provides a threaded hole for a bolt or screw to be inserted.

Rivet nuts are preferred over traditional nuts and bolts in some applications because they distribute load more evenly and provide a stronger, more secure connection. They are commonly used in aerospace, automotive, and electronics industries, among others.
