Do Nylon set screws tend to back out less than metal ones? I know from a previous thread purple Loctite or pipe dope were recommended for metal ones, but thinking if the nylon set enough I would rather use them then fiddle with Loctite.

I think I found a source for them, but looks like they come in packs of $50, not big issue. Might pop into my local hardware store and see if they have them individually.

Any constructive help would be appreciated.
