I need to put a momentary on switch in my dashboard, and the one I

How do you tighten this? I don't see how fingers can do as good a job
as a wrench did with the hex nut, and pliers will scratch it up.

I could find an old hex nut, but I'd rather use the pretty round one,
if I can.


Rob a hex from anothe switch, or grind 2 diametric notches and use
circlip pliers
