Professional Applications & Engineering Value

This M8 tab lock washer delivers critical engineering solutions where vibration-induced fastener failure is a primary concern. Manufactured from 18-8 stainless steel, it provides excellent corrosion resistance for outdoor equipment, marine applications, and chemical processing facilities. The DIN 93 compliant design with precise 8.4mm internal diameter ensures perfect alignment with M8 fasteners, while the 8mm tab width creates positive locking action that eliminates the need for additional locking mechanisms. This metric lock washer is particularly valuable in automotive assembly, industrial machinery, and electrical enclosures where maintenance downtime must be minimized. The combination of Rockwell B70 hardness and optimized 0.75mm thickness provides reliable spring tension that maintains bolt preload even under extreme operational vibrations.

Specification Summary & Compliance
