Professional Applications & Engineering Value

These M10 external tooth lock washers deliver critical vibration-resistant fastening solutions for demanding industrial applications. Manufactured from 18-8 stainless steel, they provide exceptional corrosion resistance in chemical processing, marine, and outdoor equipment where environmental factors degrade ordinary fasteners. The external tooth configuration according to DIN 6798 ensures maximum biting action into both the bolt head/nut and bearing surface, creating a mechanical lock that maintains clamp load in high-vibration machinery, automotive assemblies, and power transmission systems. The precisely controlled 0.8-1.0mm thickness provides consistent spring tension while the metric dimensions ensure seamless integration with European equipment designs, eliminating the need for retorquing maintenance in critical joints.

Specification Summary & Compliance

This external tooth lock washer features dimensional specifications of 10.5mm ID × 18mm OD × 0.8-1.0mm thickness, engineered to DIN 6798 standards for precise tooth geometry and performance. Manufactured from 18-8 stainless steel, the washer complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted international trade. The external tooth location provides optimal locking action for M10 screw applications while maintaining the material's inherent corrosion resistance and mechanical properties.
