Metric Low Carbon Steel Washer Frequently Asked Questions

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

What are metric low carbon steel washers?
Metric low carbon steel washers are general-purpose flat washers manufactured from low carbon steel (typically 1008 through 1020 grade), dimensioned in millimeters for metric fastener assemblies. They are the most economical metric washer choice for general industrial, construction, and mechanical applications where corrosion resistance is not a primary requirement.

What finishes are available for metric low carbon steel washers?
Metric low carbon steel washers are available in plain (oiled), zinc plated (clear or yellow chromate), and phosphate finishes depending on the corrosion resistance required. For outdoor or corrosive environments, metric stainless steel washers are the better choice. Contact us to specify your finish requirement when ordering.

What metric sizes are your low carbon steel washers available in?
Superior Washer stocks metric low carbon steel washers in standard DIN 125, DIN 9021, and ISO 7089/7090 sizes to fit M2 through M30 and larger metric fasteners. Custom metric sizes outside the standard range are also available to order.

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

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