Professional Applications & Engineering Value

This M20 nylon flat washer delivers critical performance advantages where electrical insulation and chemical resistance are paramount. The off-white nylon plastic construction prevents galvanic corrosion between dissimilar metals while providing reliable isolation in electrical enclosures, control panels, and marine applications. With consistent 2.7-3.3mm thickness and metric dimensions, it ensures uniform load distribution and vibration resistance in automotive, HVAC, and industrial machinery assemblies. The material's inherent lubricity allows for smoother installation while protecting sensitive surfaces from abrasion, making it ideal for repeated maintenance cycles.

Specification Summary & Compliance

Manufactured to standard metric dimensions (21mm internal diameter × 37mm outer diameter) with 2.7-3.3mm thickness tolerance. Features Rockwell R120 hardness for consistent performance and complies with RoHS 3 (2015/863/EU) environmental directives. Temperature rating spans from -40°F to 180°F (-40°C to 82°C), ensuring reliability across most industrial operating conditions. Designed specifically for use with M20 screw sizes in metric fastener systems.
