Professional Applications & Engineering Value

This M6 split lock washer delivers critical vibration resistance in industrial applications where mechanical fasteners face constant dynamic loads. The galvanized steel material provides essential corrosion protection while maintaining the spring tension needed for reliable locking performance. Engineered to DIN 127B standards, this metric lock washer ensures precise dimensional compatibility with M6 fasteners in machinery, automotive assemblies, and electrical enclosures. The Rockwell C44 hardness enables the washer to maintain its locking force through thermal cycling and mechanical stress, preventing costly downtime from fastener failure. Its split lock design creates continuous spring action that compensates for material relaxation and vibration-induced loosening in heavy-duty applications.

Specification Summary & Compliance

This standard split lock washer features precise dimensions with 6.5mm internal diameter, 11.8mm outer diameter, and controlled thickness between 1.5-1.7mm. Manufactured to DIN 127B specifications for metric fastening systems, it ensures dimensional accuracy and reliable performance. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting current environmental and substance restriction requirements. The Rockwell C44 hardness specification guarantees consistent mechanical properties and durability across production batches.
