FAQ
What is a rivet nut used for?
It creates a threaded hole in thin materials you can only reach from one side — sheet metal, tubing, enclosures — so a bolt or machine screw can be fastened into it.
Do I need a special tool for rivet nuts?
Yes. A rivet-nut setting tool (manual lever or powered) pulls the body to bulge it behind the panel. Small sizes can be set with a bolt and nut in a pinch.
