These were a bit of a pain to install. Watched a YouTube video and that guy didn’t have nearly as much trouble as I did. I could not get the rivnuts in without taking a dremel to knock down some of the bed liner in the holes. I then tried the instructional method of just torquing the bolt (using a torque wrench), but the rivnut started to spin/round out the hole before it got anywhere close to crushing. So then I tried the poor man’s tool using two wrenches and a nut, but that was only going to strip the threads if I kept trying (lube may have been the key that I didn’t read until just now). I ended up getting the proper tool at Harbor Freight which worked wonderfully. Those rivnuts are now as secure as they could possibly be. I don’t think you’d be able to sufficiently crush the included rivnuts using any other method, at least not if you want the most secure attachment you can get with rivnuts.
