Professional Applications & Engineering Value

This M14 split lock washer is engineered to address critical vibration-induced loosening in dynamic industrial systems. The zinc-plated steel material combines corrosion protection with high tensile strength, ideal for automotive, machinery, and structural applications exposed to moisture and mechanical stress. Its DIN 127B-compliant split design exerts constant radial pressure, maintaining clamp load in bolted joints subjected to cyclic loads or thermal expansion. With a Rockwell C44 hardness, it resists wear and maintains locking force in high-torque scenarios, reducing maintenance frequency and downtime. The precise 14.7mm ID and 24.1mm OD ensure perfect fitment with M14 fasteners, enhancing assembly reliability in conveyor systems, engine mounts, and heavy equipment where safety is paramount.

Specification Summary & Compliance

This washer features a 14.7 mm inner diameter, 24.1 mm outer diameter, and 2.8-3.2 mm thickness with standard metric tolerances. It conforms to DIN 127B specifications for split lock washers and is manufactured from zinc-plated steel with a Rockwell C44 hardness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial use.
