Professional Applications & Engineering Value

This M22 split lock washer delivers critical engineering solutions for vibration-prone industrial applications where fastener security is paramount. The curved split design creates continuous spring action that compensates for thermal expansion, material relaxation, and dynamic loading conditions common in heavy machinery, automotive assemblies, and construction equipment. Manufactured from zinc-plated steel with Rockwell C44 hardness, this DIN 128A compliant washer maintains its locking capability through repeated stress cycles, preventing costly downtime from loosened connections. The precise metric dimensions (22.5mm ID, 35.9mm OD) ensure perfect compatibility with M22 fasteners while the environmental compliance makes it suitable for regulated industries requiring RoHS 3 and REACH compliant components.

Specification Summary & Compliance

This split lock washer features precise metric dimensions with 22.5mm internal diameter, 35.9mm outer diameter, and 3.0mm thickness, engineered to DIN 128A standards for dimensional accuracy and performance reliability. The curved split lock washer type provides optimal spring characteristics with Rockwell C44 hardness ensuring consistent mechanical properties. Manufacturing compliance includes RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance with current SVHC requirements, making it suitable for international industrial applications requiring certified metric fasteners.
