    Structural Washers

    Distribute pressure under structural screws and nuts in columns, joists, and I-beams. These thick washers are tested and certified to meet industry standards for handling high-stress loads.

    Steel—Best for dry environments since moisture will cause these washers to rust.
    Corrosion-Resistant Galvanized Steel—These washers combine the strength of steel with the rust resistance of stainless steel. They're an economical alternative to 18-8 stainless steel in wet and outdoor environments, but they won't hold up to salt water and chemicals.
    Highly Corrosion-Resistant Zinc-Flake-Coated Steel—With 5 times the corrosion resistance of zinc-plated steel, these withstand rust as well as 316 stainless steel. They have been tested to extreme standards, including 720 hours of salt spray. They are similar to Magni-coated washers.
    Material Certificate—Washers include a report with a traceable lot number.
    For Fastener Strength Grade/Class—If you require screws or nuts with a specific fastener strength rating, make sure your washer matches the grade or class.

    Square Washers

    With flat sides, these washers fit into slots and channels and won't rotate out of position. They are also wider and thicker than most round washers, so they distribute heavier loads across a larger surface area. Square washers are commonly used to anchor heavy machinery, fasten framing to floors, and hang pipe and conduit from strut channel.

    18-8 Stainless Steel—The choice for wet and outdoor environments, these washers resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
    Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these washers won't degrade when exposed to harsh weather, salt water, and most chemicals.
    Material Certificate—Washers include a report with a traceable lot number.

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

    Rectangular Washers

    Narrower than clipped and square washers, these fit in the thinnest channels and slots. When positioned against a flat edge, they won't rotate out of position, so your assembly stays stable. Rectangular washers have a large surface area to withstand heavy loads and distribute pressure evenly under nuts and screws. They are commonly used to anchor heavy machinery, fasten framing to floors, and hang pipe and conduit from strut channel.
