Another option is a device I use at times (can't remember the name at the
moment.  It's at home and I'm at work.) is a largish pair of pliers that
presses a special nut into a certain hole size.

Captive nut?

Anyway, the pliers aren't really pliers, but are designed to sort of rivet
these special nuts intp an exact sized hole; the hole size depending upon
the size of the nut.

It also presses in standoff-type nuts, which are hand for mounting a panel
or board somewhat above the main chassis.

When I first obtained this device I experimented with it to see how strong
the system was.    In a vice, and using large pliers, I bent 1/8' aluminum
well before I was able to pull the nut free.
