General Purpose Washers
Use these washers to evenly distribute the load under bolt or screw heads and nuts when fastening. They can also act as spacers.
316 stainless steel washers have excellent resistance to chemicals and salt water. They may be mildly magnetic.
18-8 stainless steel and 17-7 PH stainless steel washers have good chemical resistance and may be mildly magnetic.
Zinc yellow-chromate and chrome-plated steel washers are corrosion resistant in wet environments.
USS washers generally have a larger ID and OD than SAE washers.

USS Washers
USS washers generally have a larger ID and OD than SAE washers.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic. Hot-dipped galvanized steel washers are 10 times as corrosion resistant as zinc-plated washers.
Black corrosion-resistant-coated steel washers resist chemicals and withstand 1,000 hours of salt spray.
