    Countersunk Insulating Sleeve Washers

    Image of Product. Bottom orientation. Insulating Washers. Countersunk Insulating Sleeve Washers.
    Flat- and oval-head screws sit flush within these insulating washers, so they won't stick out and snag on objects. Washers cover the screw head and a portion of the threads to block electrical current and prevent short circuits. They also extend the life of your assembly by preventing galvanic corrosion, which is when two different metals rust more quickly due to contact with each other.
    Nylon—Our most versatile insulating washers, these block unwanted current in everything from switches and circuit breakers to control panels and electric motors.

    Countersunk Tooth Lock Washers

    These washers grip flat- and oval-head countersunk screws, so you get a secure hold without overtightening. They resist loosening in applications with constant motion, such as conveyors. Tooth lock washers typically can't be reused because the teeth often get bent when tightened.
    External Tooth
    Image of Product. Front orientation. Lock Washers. Countersunk Washer, Tooth Washer, External Tooth.
    Teeth on the outside edge bite into both the screw head and the mating surface to lock the assembly in place. 
    Wear-Resistant 400 Series Stainless Steel—These grip hard material better than other types of stainless steel. They are not as corrosion resistant as 18-8 and 316 stainless steel, so they are best for environments that experience occasional moisture.
    Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
    Black-Oxide Steel—Typically chosen for their appearance, these washers have a dark, matte coating that creates a finished look. They offer minimal corrosion resistance, so they're best for dry environments.
    DIN 6798—Best for slightly bumpy or irregular surfaces because the teeth are angled to make even contact with the material.
