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.
At one-third the weight of steel, aluminum washers are the lightest option. They will not rust in wet environments.

Metric Electrical-Insulating Plastic Washers
These washers are excellent electrical insulators.
Hard fiber washers are resistant to organic solvents and petroleum-based oils.

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.
Delrin® acetal plastic washers combine a slippery, wear-resistant surface with good strength and rigidity.
