This is a very minor issue, but this group gives such great advice I
thought I'd ask anyway.
The metal nuts and washers securing the grill on the outside unit of my
heat pump rust over time. Not a big a deal. I just replace them.
However, I was wondering if I could use nylon washers and nuts instead.
They wouldn't rust and they might help to dampen vibrations from the
grill. Right now there is a metal flat washer, a lock washer, and a
nut. I didn't see any nylon lock washers so I'd be using a nylon flat
washer, a metal lock washer, and a nylon nut,
Here's a picture of the outdoor unit and the nylon washers and nuts.

In general, are nylon fasteners just as good (or better?) than metal
for outdoor applications subject to weather?
