Metric Stainless Steel Washer Frequently Asked Questions

Below are answers to some of the most common questions about metric stainless steel washers.

What are metric stainless steel washers?
Metric stainless steel washers are flat washers manufactured from austenitic stainless steel (typically Type 301, 302, or 304), dimensioned in millimeters for metric fastener assemblies. They offer excellent corrosion resistance without coatings or plating, making them the preferred metric washer choice for outdoor, marine, food service, pharmaceutical, and other corrosive environments where metric fasteners are specified.

What stainless steel grade do your metric washers use?
Superior Washer metric stainless steel washers are manufactured from Type 301, Type 302, or Type 304 austenitic stainless steel. All three grades provide reliable corrosion resistance for most applications, with Type 301 offering higher strength for formed or spring-style configurations. For elevated chloride environments such as marine or coastal exposure, metric 316 stainless steel washers offer superior chloride resistance and can be produced to order.

What metric sizes are your stainless steel washers available in?
Superior Washer stocks metric stainless steel washers in standard DIN 125, DIN 9021, and ISO 7089/7090 sizes to fit M2 through M30 and larger metric fasteners. The catalog covers a broad range of thicknesses for both narrow and wide-OD metric washer configurations. Custom metric sizes are available to order.

When should I use metric stainless steel washers instead of metric zinc-plated steel?
Metric stainless steel washers provide inherent, permanent corrosion resistance that does not depend on a coating. Metric zinc-plated steel washers will corrode when the zinc is scratched, worn, or exposed to chlorides or prolonged moisture. For outdoor, marine, food processing, medical, or long-term service applications, stainless steel is the correct choice.

Can you produce custom metric stainless steel washers?
Yes. We manufacture custom metric stainless steel washers to your exact millimeter OD, ID, and thickness specifications. Contact us via the Quick Quote form or call NY (631) 273-8282 or SC (803) 366-3250.

Are your metric stainless steel washers made in the USA?
Yes. All metric stainless steel washers are manufactured in the United States under our ISO 9001:2015 certified Quality Management System. Material certifications are available upon request.
