PEM nuts, or something like that for sheet metal

To everyone, I did get the message! Ended up buying a Rivet Nut tool, plus a pile of extra rivnuts. May still play with some press fit studs, just because, sometimes you don't feel like a nut.

That's great, you won't regret it.
Of course, before, tightwad me simply abused some 5mm pop-rivets into becoming M3 tapped.
I will also be buying the tool.

Ended up using both PEM nuts and rivnuts on the ELS motor control box. You all are right, once you have the nuts and tools, there's lots of places to use them. Used PEM nuts to flush mount the stepper motor driver and rivnuts to mount the fan guard/filters.
