Riveting pcb holes - engineering type input sought!

[mekanik]

Although the link to the intended rivets gives a reference (h) for the wall thickness the seller does not specify a size. Thread depth for 3mm thread is 0.3mm so it is going to have to be about 0.5mm wall thickness to give you a bit of lee way.
Can to send a quick sketch on how you need to use the holes for fixing and why you cant solder a nut/plate to the board.

For now, I'd rather not post my drawings, but I can't solder a nut becuase like I say it's single sided pcb ....and on the copper side of the pcb, the enclosure will be butting up against the pcb surface.....if I soldered a nut on that particular side, then there's be a gap equal to the height of the nut that was soldered onto the pcb (which would look awful)

Sorry can't see your logic there, even if you use the hollow rivet method i think you will find that they protrude from the board also, and forgive me if i am wrong but all the pcb assemblies i have seen the wires from the components also protrude through the board with a solder fillet.
But i am only a klanky so what do i know.
Good luck on whatever you decide.
