    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.
    Corrosion-Resistant Galvanized Steel—These washers combine the strength of steel with the rust resistance of stainless steel. They're an alternative to 18-8 stainless steel in wet and outdoor environments, but they won't hold up to salt water and chemicals.

    Coil Lock Washers

    Image of Product. Front orientation. Lock Washers. Coil Washer.
    Washers flatten under pressure and push against the nut or screw to stop it from backing out. The double coil adds more tension than split lock washers for a tighter hold on materials that contract and expand, such as plastic and wood. These washers are reusable a handful of times, but their holding power decreases with each use.
