• Non-conductive nylon construction eliminates galvanic corrosion risks when used with dissimilar metals

Professional Applications & Engineering Value

This M8 nylon plastic flat washer delivers critical engineering solutions where metal fasteners fall short. The off-white nylon material provides essential electrical insulation in control panels, automotive electronics, and telecommunications equipment, preventing costly electrical failures. Its corrosion-resistant properties make it ideal for marine applications, food processing equipment, and chemical environments where metal washers would deteriorate. The metric dimensions (8.4x18mm) ensure precise fit with M8 fasteners while the 1.8-2.2mm thickness maintains consistent spacing and vibration damping. Engineers specify this plastic flat washer to solve galvanic compatibility issues, reduce assembly weight, and provide reliable performance across extreme temperature ranges from industrial freezers to engine compartments.

Specification Summary & Compliance

This metric flat washer features precise dimensional tolerances with 8.4mm inner diameter and 18mm outer diameter, specifically designed for M8 screw applications. The nylon plastic construction provides Rockwell R120 hardness rating for consistent mechanical performance. Manufactured in compliance with RoHS 3 (2015/863/EU) standards, ensuring environmental safety and regulatory compliance. The washer maintains structural integrity across the specified temperature range of -40°F to 180°F, making it suitable for various industrial and commercial applications requiring reliable non-conductive spacing solutions.
