Product description:
These steel rivet nuts are zinc yellow-chromate plated for corrosion resistance. A ribbed body holds the nut in place so it won't turn when tightening a screw. Also known as blind inserts, they can be installed when you have access to only one side of the material. Install in a drilled hole using a rivet nut tool. The tool collapses the nut, creating a backside flange that holds the nut to the material.
