Let me put it this way...I am building an airplane and using the nylon
insert nuts for most applications with a few critical exceptions where
only a castle nut and cotter pin is acceptable. I don't use and
wouldn't even consider using lock washers on anything. On the nylon
insert lock nuts I add a dab of bright colored paint across the thread
and onto the nut in one small area. This will give a visual clue if
the nut should move following installation.
PS: If you are really into the belt and suspenders approach, there
are castle nuts with nylon locking inserts as well.
