Professional Applications & Engineering Value

This M12 nylon flat washer delivers exceptional engineering value in demanding industrial environments where metal fasteners fall short. The black nylon plastic construction provides inherent corrosion resistance, making it ideal for chemical processing, marine, and outdoor applications where moisture and corrosive elements are concerns. Its excellent electrical insulation properties prevent current leakage in electrical assemblies, while the temperature range from -40°F to 180°F ensures reliable performance in both freezing and elevated temperature conditions. The metric flat washer design following ASME B18.22M specifications guarantees precise load distribution and consistent performance in industrial plastic washers applications, from machinery assembly to electronic enclosures.

Specification Summary & Compliance

This metric flat washer features precise dimensions with 13.4mm internal diameter, 25.1mm outer diameter, and 2.4-2.7mm thickness range, engineered for M12 screw applications. Manufactured to ASME B18.22M standards for dimensional accuracy and performance reliability. The washer is RoHS 3 (2015/863/EU) compliant and features Rockwell R120 hardness rating, ensuring consistent quality and environmental responsibility in industrial applications.
