Time will tell.. I'm sure it's fine for the application. Thanks for
everyone's comments, especially those regarding the aluminum riv-nuts.
I will look into those for next time.

Cheers,

Riv-nuts cost peanuts and go on with a pop rivet gun.

But if you were paranoid about electrolytic corrosion, there is a
species of rubber expanding nut with an internal metal threaded
insert. That might suit some low strength applications too.


Indeed. These are commonly used (or were...) for mounting air
conditioner condensers in cars, where galvanic corrosion is also a
problem. Unfortunately, however, the only ones I have seen have the
threaded insert made of brass. Not a good choice in a marine environment.
