Professional Applications & Engineering Value

This Nylon Plastic Flat Washer is engineered to address common industrial challenges such as galvanic corrosion, electrical isolation, and weight reduction in assemblies. Its nylon material inherently resists moisture, chemicals, and UV exposure, making it a superior choice for outdoor, marine, and electrical insulation applications. The precise inch system dimensions (0.162" ID x 0.312" OD) ensure a perfect fit for No. 6 screws, preventing loosening and distributing clamp load evenly to protect sensitive surfaces. With a temperature range from -40°F to 180°F, it maintains flexibility and strength in both freezing and moderately high-heat environments, reducing the risk of brittle fracture or melting. Ideal for industrial machinery, automotive components, and consumer electronics, this washer simplifies compliance and boosts reliability in demanding applications.
