A rivet nut tool is a specialized tool used to install rivet nuts. Rivet nuts are fasteners that are used to secure two or more pieces of material together. They are similar to rivets, but they are threaded on the inside so that they can be used with screws or bolts.

Rivet nuts are installed using a rivet nut tool, which is a handheld tool that clamps onto the material and inserts the rivet nut into the hole. The tool then pulls the rivet nut tight, creating a secure connection. Rivet nut tools are available in a variety of sizes and styles to accommodate different materials and applications.
