Everything you need to add threads to sheet metal, these assortments contain twist-resistant rivet nuts, mandrels, nosepieces, and a plier-style installation tool. The nuts have a ribbed body that grips surrounding material to hold them in place, keeping them from spinning as you tighten screws. They create reusable threads in surfaces that are too thin to be tapped. Also known as blind inserts, installation requires access to just one side of your material. The flange distributes the load and holds the nuts against the surface. All are steel with a zinc yellow-chromate plating to resist corrosion in wet environments.

To install, thread a rivet nut onto the mandrel, insert the nut into a drilled or punched round hole, and squeeze the handles to secure the nut.

Use these rivet nuts for light duty fastening in low-clearance applications. Assortments include rivet nuts, mandrels, and an installation tool. Rivet nuts have a cadmium plating that provides corrosion resistance and adds lubricity so they collapse smoothly. The threaded portion is drawn into the sleeve when installed, creating pressure against the hole to secure the nut.
