Professional Applications & Engineering Value

These blue-dyed steel split lock washers deliver critical vibration resistance in mechanical assemblies where dynamic loads threaten fastener integrity. The DIN 127B standard ensures precise dimensional control and spring characteristics, providing reliable locking performance in automotive, machinery, and electronic enclosures. The split lock washer design creates continuous outward pressure that counters rotational forces, while the blue-dyed finish offers both visual identification and basic protection. Engineered for M3 screw applications, these metric lock washers solve common industrial challenges of maintenance reduction and assembly reliability in vibration-prone environments.

Specification Summary & Compliance

Manufactured to DIN 127B specifications with precise dimensions: 3.4mm inner diameter, 6.2mm outer diameter, and 0.7-0.9mm thickness. These split lock washers meet international regulatory standards including RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance as of June 14, 2023. The metric system design ensures compatibility with standard M3 fasteners and industrial assembly requirements.
