    Reinforcing Sleeve Washers

    These sleeve washers are a great solution when your nut or screw is harder than the material you're mounting it in. They reinforce the top of the hole to prevent soft material from collapsing as you tighten.

    Split Lock Washers

    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.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these washers won't rust when exposed to moisture. However, they can't hold up to the harsh chemicals that 316 stainless steel can.
