    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 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.
    Extreme-Strength High-Temperature Carbon-Filled PEEK—Second only to phenolic in terms of strength, these washers stand up to high-stress applications. They won't melt or deform when exposed to high temperatures up to 500° F.
    Extreme-Temperature Polyimide—Our most temperature-resilient plastic washers. These won't deform or lose strength at temperatures as low as -450° F and as high as 750° F to handle everything from liquid nitrogen to heating elements. They are also good electrical insulators.
    Electrically Insulating Ultem PEI—Our best electrical insulators, these washers are often used to secure components in circuit-breaker housings and semiconductors.

    These washers won't melt, stick, or become brittle, even when exposed to temperatures as high as 1050° F. They make excellent insulators and are often used to secure electrical connections in transformers. Mica can chip and flake due to wear, however, so these washers are not recommended for high-vibration applications.

    Ultra-High-Temperature Ceramic Washers
    3D CAD models available

    Image of Product. Front orientation. Washers. Ultra-High-Temperature Ceramic Washers.
    Our most heat-resistant washers, even at blistering temperatures up to 3000° F. They distribute pressure evenly under nuts and screws in industrial furnaces, kilns, and other extreme-temperature environments. Ceramic may crack or dent if subjected to hard bumps, however, so these washers are not recommended for high-vibration applications.
