• Standard thickness range (1.5-1.7mm) offers reliable performance across various clamping applications

Professional Applications & Engineering Value

These M6 split lock washers deliver critical vibration damping in high-stress mechanical systems where DIN 127B standardization is required. The steel material with Rockwell C44 hardness provides optimal spring characteristics that maintain constant preload, preventing joint failure in automotive assemblies, industrial machinery, and electrical enclosures. The split lock washer design creates radial tension that counters rotational forces, making them ideal for metric fastener applications subject to thermal cycling and dynamic loads. Their RoHS 3 and REACH compliance ensures they meet the strictest environmental standards for manufacturing and industrial maintenance operations.

Specification Summary & Compliance

Manufactured to DIN 127B specifications with precise metric dimensions: 6.5mm internal diameter, 11.8mm outer diameter, and 1.5-1.7mm thickness range. The standard split lock washer design ensures consistent performance for M6 screw applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting current environmental standards for industrial components.
