[KX3][2M] Assembly Advice - Going Nuts!

[Ozy]

I am installing my third 2M module on a KX3 for a friend.   On this particular unit, the nut that I guess was being held on by some adhesive I never noticed, fell off the back of the FET heat sink.   I’m having a stickler of a time trying to figure out a clever way to hold the nut on there so I can re-insert the board and get the lock screw through the side of the case.  (Figure 20, Page 27)

Any wise men around have any sage advice?

Chris,

This is not supposed to happen (first case I've heard of), so you could just request a replacement 2-meter module. That said, you could probably re-glue the nut in place temporarily using a tiny bit of epoxy, avoiding the threads. Once the TO220 device tab is secured by the screw, the adhesive no longer serves any function.

Hot melt glue might be more forgiving (glue on the threads) or double
sided tape with a punched hole for the screw.
When I built Heath Kits and "real work" I would use tape on my finger so
that I could hold the nuts in place while I attached the screw...
