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.
Lightweight Aluminum—At one-third the weight of steel or brass, use these nuts in applications with strict weight limits, such as robotics and aerospace parts. They resist rust almost as well as stainless steel but aren't as strong.
