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, the coating has been tested to extreme standards, including 1,000 hours of salt spray, to hold up in wet and outdoor environments. 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.

Steel Hex Head Screw Kits
 |  |  |
Fully Threaded | Partially Threaded |
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.

Keep a range of hex head screw, nut, and washer sizes on hand for a variety of jobs. The screws in these assortments have heads with six flat sides to keep wrenches and sockets slipping and rounding off the drive.
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.
Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
Steel—Unfinished steel screws are best for dry environments, since moisture will cause them to rust. They require little surface prep before applying a finish, so you can apply your own paint or coating.
