Professional Applications & Engineering Value

Engineered to address critical vibration-induced loosening in industrial settings, this M16 split lock washer delivers robust performance through its blue-dyed steel construction and DIN 127B standardization. The split lock mechanism exerts continuous spring tension, effectively resisting rotational forces in machinery, automotive assemblies, and heavy equipment. With a Rockwell C44 hardness, it maintains structural integrity under repeated stress cycles, while the precise metric dimensions (17mm ID, 27.4mm OD) ensure compatibility with M16 fasteners. Ideal for applications requiring reliable locking security, such as conveyor systems, engine mounts, and structural frameworks, this washer minimizes the risk of fastener failure, enhancing operational safety and reducing maintenance interventions.

Specification Summary & Compliance
