Plastic Washers

All of these washers are lightweight, nonconductive, and naturally rust resistant. They are commonly used in electronics and automation applications to take the pressure off screws and nuts and protect mounting surfaces.

High-Strength Glass-Filled Nylon—Stronger than plain nylon, but not quite as strong as PEEK. These washers will swell and weaken when exposed to moisture, so they are best for dry environments.
