You can install a nutsert without fancy tools.
Drill the hole very accurately.
Insert the rivnut.
Assemble the bolt, nut and washer as shown.
While holding the head of the bolt, tighten the nut to set the insert. A little lube on the bolt threads help.

I received my order of Pemnuts and Rivnuts earlier today and was fooling around with them on a piece of scrap metal. Pemnuts worked well, but I had easy access to both sides of the workpiece. But when I tried the Rivnuts using this method, the head of the bolt would just break off. I drilled the hole using the correct bit and a press, so it's clean and accurate. I used 10-32 stainless nuts and bolts, lube, and a plain steel Rivnut. Anyone tried this method successfully and have any idea what I did wrong?
