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.
Black-oxide steel washers have mild corrosion resistance in dry environments.
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.
Often used with nuts, bolts, and other fasteners, washers are thin plates with central holes used to distribute the pressure load between two joining surfaces. They also keep nuts or bolts from driving into the material of the surfaces being joined. Vibration, friction, and general use can cause standard threaded fasteners to come loose over time, but lock washers are designed to maintain a secure connection. This guide reviews how to use lock washers and the different types there are.
