Rivnuts don't have a nut. What I showed in the picture is how you install them without a special tool. Thread a nut onto the bolt, insert through hole in a place of metal, screw your rivnut onto that. Place the rivnut in hole. Hold the bolt with one wrench and turn the nut away from the head of the bolt. You can feel when the rivnut is tight,the nut will be harder to turn, DON'T give it "an extra turn for good measure", it will distort the rivnut and make it less strong.
Be sure to use a bolt that is long enough to engage all of the threads of the rivnut.The metal strap will keep the rivnut from turning. Make sure you drill the correct size hole, read the specs. if you have to, buy the correct size bit that the specs say. LOOK IT UP.
