I couple of times I had success with placing a washer on the opposite side of the chassis
lip from the pemnut then using a stainless cap screw I inserted it into the threads
drawing it tightly against the washer. This effectively "set" the nut in the
aluminum lip. Then back out the cap screw and you should be "set" if you can
pardon the pun!

I am finishing up several chassis that hold various components for my EME system. I have
used self-clinching nuts ("Pemnuts") for a long time on flat sheets, no problem.
Now I want to install self-clinching nuts on the lip of a chassis. There is no way to
get a shop press anvil on the back side to support it. I considered Vice-grips but they
leave an ugly gouge. There ought to be a special hand tool but I can't find any.
Note, I'm not talking about rivet-nuts... that's a different problem. I'm
referring to this kind:
