    Split Lock Washers

    Image of Product. Front orientation. Lock Washers. Split-Lock Washer.
    Stop nuts and screws from loosening due to mild vibration. As you tighten, the uneven ends bite into the nut or screw so it won't back out. While they're not as vibration resistant as other lock washers, they are a great fit for electrical panels, light fixtures, and other light duty assemblies. Split lock washers are not reusable, and they only work with fasteners that have right-hand threads.
    Highly-Corrosion-Resistant Silicon Bronze—The choice for marine environments, these washers won't rust or deteriorate when submerged in salt water. They resist corrosion as well as 316 stainless steel, but are not quite as strong.

    Tooth Lock Washers

    Grip tighter than split lock washers to prevent nuts and screws from loosening in applications with constant movement, 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. Tooth Washer, External Tooth.
    Teeth on the outside edge bite into both the fastener and the mating surface for a stronger hold than internal-tooth lock washers. However, they may mar your material and snag on objects. Pair these washers with nuts and screws that are large enough to make contact with the teeth, such as pan, button, and binding head screws.
    Highly-Corrosion-Resistant Phosphor Bronze—Stronger and more wear resistant than silicon bronze, but with the same excellent corrosion resistance. These washers won't rust or deteriorate when submerged in salt water, so they're a good fit for marine environments.

    Internal Tooth

    Internal teeth dig into the nut or screw to prevent it from backing out. Unlike external-tooth lock washers, these have a smooth outside edge, so they are less likely to mar your material or snag on objects. However, they don’t grip quite as well. Pair them with fasteners that have small diameters, such as fillister and cheese head screws.

    Mil. Spec. Tooth Lock Washers

    These washers are manufactured and tested to strict U.S. military standards for material and construction. They resist vibration better than split lock washers to prevent nuts and screws from loosening in applications with constant movement, such as conveyors. Tooth lock washers typically can't be reused because the teeth often get bent when tightened.

    Wave Spring Lock Washers

    Image of Product. Front orientation. Lock Washers. Wave Washer, Spring Lock Washer.
    The wavy shape flexes like a spring to keep nuts and screws secure on slightly uneven surfaces. These washers add a small amount of tension to stop fasteners from backing out due to mild vibration. While they don't hold as well as other lock washers, they do grip slightly better than curved washers. They work best in electrical panels, light fixtures, and other light duty assemblies. Since these washers hold their shape when untightened, you can reuse them a handful of times without losing strength.
    Highly-Corrosion-Resistant Phosphor Bronze—Stronger and more wear resistant than silicon bronze, but with the same excellent corrosion resistance. These washers won't rust or deteriorate when submerged in salt water, so they're a good fit for marine environments.
