Professional Applications & Engineering Value

This M3 split lock washer delivers critical anti-loosening performance in demanding mechanical assemblies where vibration and dynamic loads compromise fastener integrity. The curved spring design creates continuous radial pressure that counters rotational forces, while the black-oxide steel construction provides essential corrosion resistance in industrial environments. Engineered to DIN 128A specifications, this metric lock washer ensures precise dimensional compatibility with M3 fasteners in machinery, automotive systems, and electronic enclosures. The Rockwell C44 hardness maintains spring characteristics under repeated compression cycles, making it ideal for maintenance-critical applications where disassembly and reassembly are frequent. This industrial washer solves common vibration-induced failure points in production equipment, transportation systems, and power transmission assemblies.

Specification Summary & Compliance

This split lock washer features precise metric dimensions with 3.1mm inner diameter, 6.2mm outer diameter, and 0.6mm thickness, engineered to DIN 128A standard for dimensional accuracy and performance consistency. The manufacturing process ensures proper curved spring washer geometry that delivers reliable locking action. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, this component meets international environmental and safety standards for industrial use across global markets.
