Here we go, the professional has entered the comments.

The strength of PEM nuts is so much better than rivnuts. I designed parts for a missle system that had to be transported, and possibly air dropped, and rivnuts were not going to work when you have to handle 20g.

I had to knock a few of these out of sheet-metal case and man I did not expect that kind of resistance from something with such a tiny contact area in 0.8 mm sheet metal.

It’s wild how strong they are.

But it seems you need a tool that can apply a force from two sides of the plate. This is not easy if the plate is large and the hole is in the middle.

That’s true, but people put rivnuts all over the place where they aren’t blind. PEM is a much better choice when it’s not blind.

Used to use PEM nuts for mounting industrial controls onto panels.

Worked at a place that made the enclosures for industrial controls and we used PEM for all the standoffs.
