SAE washers generally have a smaller ID and OD than USS washers.

316 stainless steel washers have excellent resistance to chemicals and salt water. They may be mildly magnetic.

18-8 stainless steel washers have good chemical resistance and may be mildly magnetic. Black-oxide 18-8 stainless steel washers have a matte-black finish.

Zinc-plated, zinc yellow-chromate plated, and chrome-plated steel washers are corrosion resistant in wet environments.

Hot-dipped galvanized steel washers are 10 times as corrosion resistant as zinc-plated washers.

Black Corrosion-resistant coated and zinc-flake-coated steel washers resist chemicals and withstand 1,000 hours of salt spray.

In addition to resisting rust in wet environments, copper and brass washers are electrically conductive. At one-third the weight of steel, aluminum washers are the lightest option. They will not rust in wet environments.

Square washers fit into slots and channels and have flat sides to keep them from rotating. They are wider and thicker than most round washers, making them good for distributing heavy loads.

Black-oxide steel washers are mildly corrosion resistant in dry environments.

Zinc-plated steel washers are corrosion resistant in wet environments.

Galvanized steel washers are 10 times as corrosion resistant as zinc-plated steel washers.

18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.

Zinc- and zinc yellow-chromate plated steel washers are corrosion resistant in wet environments.

Washers that meet ASME B18.21.1 adhere to strict dimensional standards. Steel washers also meet standards for material properties.

Compared to standard split lock washers, these are thicker and have larger outside diameters. As a screw is tightened, they flatten to add tension to the joint and prevent loosening from small amounts of vibration.

Steel washers are known for their strength. They're zinc yellow-chromate plated for corrosion resistance in wet environments.

Also known as conical washers, these have a slightly cupped shape that gives them spring-like flexibility to grip tighter than split and tooth lock washers. They minimize loosening from wear, temperature changes, and vibration. Load-rated Belleville disc springs are also available.

Zinc-plated steel washers have an outer layer of zinc that protects the inner steel from rust in wet environments and extends the life of the washer.
