    Image of Product. Front orientation. Washers. Mil. Spec. Washers.
    These washers are manufactured and tested to strict U.S. military standards for material and construction. They take the pressure off screws and nuts to protect mounting surfaces.
    Brass
    Softer than most metals, brass washers won't damage other fastening components.
    Black-Oxide Brass—Typically chosen for their appearance, these washers have a dark, matte coating to create a finished look. They resist rust in wet and outdoor environments, but won't hold up to salt water and harsh chemicals.
