Nylon Flat Washer Frequently Asked Questions

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

What are nylon flat washers?
Nylon flat washers are manufactured from polyamide (nylon) engineering plastic, most commonly Nylon 6 or Nylon 6/6. Nylon washers are lightweight, non-conductive, non-magnetic, and resistant to oils, fuels, and many chemicals, making them one of the most widely used plastic washer materials across industrial, automotive, and consumer applications.

What are nylon flat washers used for?
Nylon washers serve as electrical insulators between metal components, vibration dampeners, noise reducers, protective cushions to prevent surface damage, and general-purpose non-metallic spacers. They are used in electronics, automotive assemblies, HVAC systems, and consumer products wherever a lightweight, non-conductive washer is required.

Do nylon washers absorb moisture?
Yes, nylon is hygroscopic and will absorb moisture from the environment, which can cause slight dimensional changes. For applications requiring tighter dimensional stability in wet or variable-humidity conditions, Delrin or Nylatron are better alternatives. For most general-purpose applications, nylon's moisture absorption is not a concern.

Can you make custom nylon flat washers?
Yes. Superior Washer manufactures custom nylon washers to your exact OD, ID, and thickness specifications. Contact us via the Quick Quote form or by phone.

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