    Sealing Washers

    Prevent leaks while distributing weight evenly under nuts and screws. These washers compress as you tighten to keep air and fluid in, and dust and contaminants out. Use them anywhere you need a tight seal, such as protecting electronics from moisture or keeping lubricants contained in machinery.

    Also known as crush washers, these are made of soft metal that deforms under pressure to fill gaps around the nut or screw. Often found in oil drain valves, they withstand stress and wear better than plastic and rubber washers, but aren't as leak-resistant. Metal sealing washers are not reusable.
    Aluminum—These washers are an economical alternative to copper. They have similar corrosion resistance but require more effort to crush.

    Bonded Sealing Washers

    Image of Product. Front orientation. Sealing Washers. Bonded Sealing Washers.
    These washers create a stronger seal than metal or rubber alone to lock air and fluid in, while keeping dust and contaminants out. The flexible rubber layer compresses to fill gaps, while the metal backing stops the washer from squeezing through the hole. These washers are a great solution if you have a hole larger than your fastener that you need to seal. Reuse them a handful of times, as long as the material isn't damaged.
    Aluminum and Neoprene—These washers are as corrosion resistant as stainless steel but not as strong.

    Sealing Washer Assortments

    Keep a collection of metal sealing washers on hand to prevent leaks while distributing weight evenly under nuts and screws. Also known as crush washers, these deform when tightened to lock air and fluid in, while keeping dust and contaminants out. They are not reusable.
    Labels in the lid include our part numbers, so it's easy to replenish the assortments.

    Fabric Grommets

    Add a protective metal ring to a hole so rope and cable don’t tear your tarp, cover, or curtain. To install, strike a cutting punch with a mallet to create the hole, then set the grommet using either an installation punch or a press. All of these grommets can be used outdoors. Installation tools are sold separately.

    Cutting Punch

    Hammer-Driven Installation Punch—The economical choice if you’re installing a few grommets at a time. Align the grommet base, fabric, and washer on the die (included). A few sharp taps on the punch cinch the grommet in the hole. Use a rubber or rawhide mallet rather than a metal hammer to preserve the head of the punch.
