Professional Applications & Engineering Value

This M14 external tooth lock washer delivers critical vibration-resistant fastening solutions for demanding industrial applications where safety and reliability are paramount. Engineered from 316 stainless steel, it provides superior corrosion resistance in chemical processing, marine, and food industry environments where moisture and aggressive substances are present. The external tooth configuration creates multiple biting points that dig into both the fastener and workpiece, maintaining clamp force where standard washers would fail. This DIN 6797 compliant design ensures precise dimensional control for M14 fasteners, preventing assembly issues and reducing maintenance cycles in heavy machinery, automotive systems, and structural applications where vibration-induced loosening poses significant safety risks.

Specification Summary & Compliance

This external tooth lock washer features precise metric dimensions with 15mm internal diameter, 24mm outer diameter, and 0.9-1.2mm thickness, engineered specifically for M14 screw applications. Manufactured in compliance with DIN 6797 standards for dimensional accuracy and performance requirements. The product meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) compliance for chemical safety, with verification against 233 SVHC substances as of January 2023.
