Ideal for parts that require frequent maintenance or disassembly, these rivet nuts won't spin out when you tighten or loosen a screw. Their ribbed body digs into material to prevent twisting.

Install these nuts in a drilled or punched round hole using a rivet nut tool. Thread the rivet nut onto the mandrel, then grip the tool body with a wrench as you twist the tightening nut with a ratchet. Choose an air- or battery-powered tool for fast installation or to easily switch between many different nut sizes. Length is measured from under the flange.

Add permanent threads to thin metal with our go-to weld nuts. Unlike press-fit and rivet nuts, these nuts fuse to the base metal, so they won’t twist and pull out. Three evenly spaced projections concentrate heat away from the threads to prevent them from deforming and create consistent welds. All have a collar pilot that guides the nut into the hole, holds it in place while welding, and protects the threads from weld spatter. You can also install them on thick pieces of metal.
