Professional Applications & Engineering Value

This M2 metric split lock washer is engineered to solve critical vibration-induced loosening in precision assemblies. Its DIN 127B standard design and steel material with Rockwell C44 hardness provide a robust spring action that maintains constant tension between the nut and bearing surface. This is vital in industrial applications such as small motors, electronic enclosures, and automotive components where even minor fastener failure can lead to operational downtime. The split lock washer type effectively absorbs shocks and thermal expansion, making it ideal for demanding environments that experience dynamic loads. By integrating this component, engineers enhance assembly integrity, reduce maintenance frequency, and ensure compliance with international safety standards.

Specification Summary & Compliance

The washer features a 2.4mm inner diameter, 4.4mm outer diameter, and 0.4-0.6mm thickness, manufactured to DIN 127B specifications for dimensional accuracy. It is designed for M2 screw size and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free of hazardous substances and suitable for use in regulated industries.
