Professional Applications & Engineering Value
This DIN 127B split lock washer delivers critical vibration resistance in demanding industrial environments where mechanical fasteners face constant stress and movement. The hardened steel construction with Rockwell C44 hardness ensures the spring tension remains effective through repeated loading cycles, preventing loosening in M18 fastener applications. Engineered to DIN 127B specifications, these metric washers provide reliable performance in machinery assembly, automotive systems, and heavy equipment where vibration-resistant locking is essential for operational safety and reduced maintenance intervals. The split design creates continuous opposing force that compensates for thermal expansion and material settling.
Specification Summary & Compliance
Manufactured to DIN 127B standards with precise dimensional tolerances: 19mm internal diameter for M18 screws, 29.4mm outer diameter, and 3.3-3.7mm thickness range. The hardened steel material achieves Rockwell C44 hardness for consistent spring performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted use in industrial applications across regulated markets.
