Metric Brass Washer Frequently Asked Questions

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

What are metric brass washers?
Metric brass washers are flat washers dimensioned in millimeters for use with metric fasteners. Superior Washer manufactures metric brass washers to DIN and ISO standard sizes as well as custom metric dimensions, providing excellent corrosion resistance, electrical conductivity, and an attractive appearance for plumbing, marine, electrical, and precision instrument applications. Our metric brass catalog covers over 1,055 configurations.

What DIN and ISO standards do your metric brass washers conform to?
Superior Washer metric brass washers are produced to DIN 125, DIN 9021, and ISO 7089/7090 standard dimensions where applicable, as well as custom metric sizes not covered by a specific standard. All washers carry a dimensional tolerance of +/- 0.127 mm on both ID and OD.

What size range are your metric brass washers available in?
Our metric brass washers cover ID sizes from approximately 0.91 mm through 19.15 mm and OD sizes from approximately 3.15 mm through 50.8 mm, across a wide range of thicknesses from 0.025 mm through 3.96 mm. This extensive range supports miniature, precision, and industrial metric fastener applications.

What brass alloy do you use for metric washers?
Metric brass washers are manufactured from Brass Alloy 260 (cartridge brass, 70% copper / 30% zinc), which offers the best balance of corrosion resistance, formability, conductivity, and strength for washer applications.

Can you produce custom metric brass washers?
Yes. We manufacture custom metric brass 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 brass washers made in the USA?
Yes. All metric brass washers are manufactured in the United States under our ISO 9001:2015 certified Quality Management System. Material certifications are available upon request.
