    Plastic Washers

    Image of Product. Front orientation. Washers. 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.
    Nylon—The most popular plastic washers, these are strong, durable, and economical. Nylon will swell and weaken when exposed to moisture, so these washers are best for dry environments.
    Clear Impact-Resistant Polycarbonate—Withstand bumps and vibration without cracking or denting. These washers are also clear to be less noticeable in your assembly.
    Low-Friction Impact-Resistant UHMW Polyethylene—The slippery surface reduces friction between the washer, fastener, and mounting surface to prevent sticking when fastening and loosening. These washers also resist bumps and vibration without cracking or denting.
    High-Strength High-Temperature PEEK—These washers bear heavier loads than most other plastic washers. In addition, they won't melt or deform when exposed to high temperatures up to 550° F. PEEK washers aren't very impact resistant, however, so they may crack or dent if subjected to hard bumps and vibrations.

    SAE Washers

    Originally designed for the automotive industry, these washers conform to SAE sizing standards. They generally have smaller diameters than USS washers to fit in cramped spots and are thinner to create more precise gaps. Washers distribute pressure under screws and nuts to protect your mounting surface.

    Highly Corrosion-Resistant Zinc-Flake-Coated Steel—With 40 times the corrosion resistance of zinc-plated steel, these withstand rust as well as 316 stainless steel. They have been tested to extreme standards, including 1,000 hours of salt spray. They are similar to Magni-coated washers.
    For Fastener Strength Grade/Class—If you require screws or nuts with a specific fastener strength rating, make sure your washer matches the grade or class.
