Professional Applications & Engineering Value
Our M24 DIN 127B split lock washers are engineered to solve critical vibration-induced loosening in demanding industrial environments. The hardened steel material with Rockwell C44 hardness provides exceptional spring tension that maintains constant pressure on fasteners, preventing back-off in machinery, automotive assemblies, and heavy equipment. The standard split lock design creates continuous friction against both the bolt and surface, making these metric washers ideal for applications where thermal cycling, dynamic loads, or constant vibration would compromise ordinary fasteners. With precise 25.5mm internal diameter and 40mm outer diameter, these washers ensure perfect compatibility with M24 screws while the 4.8-5.2mm thickness delivers optimal deflection for maximum locking force in mechanical systems, construction projects, and manufacturing equipment.
Specification Summary & Compliance
This split lock washer meets DIN 127B specifications with precise dimensional tolerances for metric applications. The washer features a 25.5mm internal diameter and 40mm outer diameter with 4.8-5.2mm thickness, specifically designed for M24 screw sizes. Manufactured from steel with Rockwell C44 hardness, the product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use across industrial applications while maintaining consistent locking performance and durability.
