When it comes to turning wrenches... you guys have forgotten about ten times more than I will ever know.

Ain't that the truth

That's why I use the aluminum Rivnuts instead of the steel ones - they're a lot easier to "set". I use a hex bit in my air impact, oil the threads and the flat washer, thread the screw in about halfway, position the Rivnut in the hole with the bit inserted in the allen screw, and pull the trigger; the impact spins up instantly with no load (which is why I only insert the allen head screw halfway), and when the screw/washer bottoms out against the face of the Rivnut, it clinches/mushrooms instantly. Hardly ever have to hold the O.D. of the Rivnut face - if I have to, that's why I use a small-O.D. AN washer with the allen screw - leaves room to grab the O.D. of the Rivnut with pliers.

With the steel ones, you definitely need the installation tool.

I just set some 1/4" inserts as you explained with my air ratchet and it works excellent.

I just knew there had to be a trick to it. It seem so simple now to use the air racket but I just never thought of it.Thanks again .I am still learning something new every day working with tools
