    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.
    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.
    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.

    Fiberglass Washers

    Image of Product. Front orientation. Washers. Fiberglass Washers.
    A lightweight alternative to stainless steel, these fiberglass washers have the best strength-to-weight ratio of all our nonmetal washers. Commonly used to distribute pressure under nuts and screws in building frames, they are a great fit when you need something more robust than plastic, but still have to stay within a certain weight limit.
    Material Certificate—Washers include a report with a traceable lot number.

    Plastic Unthreaded Spacers

    Image of Product. Front orientation. Spacers. Plastic Unthreaded Spacers.
    Lightweight, nonconductive, and naturally rust resistant, these plastic spacers are commonly used for electronic and automation applications.
    High-Temperature High-Strength PEEK—These are our strongest plastic spacers. They also won't degrade when exposed to high heat, so they're a good choice for transmission systems and electric battery packs. They aren't very impact resistant, however, and may crack or dent if subjected to hard bumps and vibrations.
    Military Specification—These spacers are manufactured and tested to meet strict U.S. military standards for material and construction.
