How do you use the 'Rivet Nut Tool?

To use a rivet nut tool, first select the appropriate rivet nut size and insert it into the tool's mandrel. Next, prepare the material by drilling a hole that matches the diameter of the rivet nut. Insert the rivet nut into the hole, then use the tool to pull the mandrel, which expands the rivet nut against the back side of the material, creating a secure threaded insert. Finally, release the tool to complete the installation.
