Self-Retaining Washers
A specially shaped ID grips your screw shank tightly. All of these washers are good electrical insulators.
Nylon washers are more wear resistant than polyethylene washers. They are not, however, as moisture resistant.
Polyethylene washers are softer, more flexible, and withstand moisture better than nylon washers. They are not as wear resistant.
