Steel Twist-Resistant Rivet Nuts

About twice as strong as aluminum rivet nuts, 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. Length is measured from under the flange. Installed length is the maximum length of the barrel when installed.
