Metric Nylon Washer Frequently Asked Questions

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

What are metric nylon washers?
Metric nylon washers are flat washers manufactured from polyamide (nylon) engineering plastic, dimensioned in millimeters for use with metric fasteners. They are lightweight, non-conductive, non-magnetic, and resistant to oils and many chemicals, making them a popular choice for metric fastener assemblies in electronics, automotive, HVAC, and industrial equipment where electrical isolation or surface protection is required.

What are the main applications for metric nylon washers?
Metric nylon washers are used as electrical insulators between metal components, vibration dampeners, noise reducers, and surface protection washers in metric assemblies. Common applications include electronics enclosures, automotive hardware, metric machine screws in consumer products, and any metric fastener application requiring a lightweight, non-conductive washer.

What metric sizes are available for nylon washers?
Superior Washer stocks metric nylon washers in standard DIN metric sizes to fit M2 through M24 and larger metric fasteners, as well as custom metric sizes. Contact us for specific metric size availability or to request a custom configuration.

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