    Mil. Spec. Plastic Washers

    Image of Product. Front orientation. Washers. Mil. Spec. Plastic Washers.
    These washers are manufactured and tested to strict U.S. military standards for material and construction. They are lightweight, nonconductive, and naturally rust resistant. Commonly used in electronics and automation applications, they take the pressure off screws and nuts to protect mounting surfaces.
    Chemical-Resistant High-Temperature PTFE—The most chemical-resistant plastic washers we offer, these stand up to the widest range of harsh acids, bases, solvents, and corrosive cleaners, even at temperatures up to 500° F. Their slippery surface reduces friction between the washer, fastener, and mounting surface to prevent sticking when tightening and loosening. They are also good electrical insulators.
