    Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
    Zinc-Yellow-Chromate-Plated Steel—With the same corrosion resistance as zinc-plated steel, these withstand occasional exposure to moisture.
    Highly Corrosion-Resistant Zinc-Flake-Coated Steel—With 40 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 1,000 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.

    Tension-Indicating Structural Washers

    Fasten structural screws and nuts securely without overtightening. When you see orange dye, you'll know you've applied the correct tension, so you don't accidentally strip threads. These washers distribute pressure under fasteners in columns, joists, and I-beams. They are tested and certified to meet industry standards for handling high-stress loads.
    Steel

    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.
    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.

    Everything you need for a complete, strong joint—the screws in these kits come with compatible nuts and washers. The screws have a head with six flat sides to keep wrenches and sockets from slipping and rounding off the drive. Washers distribute pressure on both sides of your material, so the nut tightens onto the screw without damaging surfaces.
    Screw length is measured from under the head.
    Medium-Strength Fastener—Your go-to screws for fastening most machinery and equipment. They have tensile strengths from 90,000 to 120,000 psi.
