About Washers

Metric General Purpose Washers
Use these metric washers to evenly distribute the load under bolt or screw heads and nuts when fastening. They can also act as spacers.
Stainless steel washers are more corrosion resistant than steel washers, and almost as strong. 18-8 and 17-7 PH stainless steel washers will hold up in humid, damp, and washdown environments, but will corrode if exposed to salt water or chemicals. 17-7 PH stainless steel washers are stronger than 18-8 stainless steel.At one-third the weight of steel, aluminum washers are the lightest option. They will not rust in wet environments.
Washers that meet ISO 7089, 7090, 7091, and 7092 (formerly DIN 125, 126, and 433), meet international standards for fastener dimensions. The ISO 7091 washers have a slightly rougher surface than a typical flat washer.

Metric Water- and Steam-Resistant Plastic Washers
Low moisture absorption and good heat resistance make these washers suitable for wet and harsh environments. All are good electrical insulators.
Fiberglass washers are stronger than Delrin® acetal plastic washers and have excellent resistance to salt water. Color ranges from light green to light tan.
