Professional Applications & Engineering Value

Engineered for demanding industrial environments, these M22 split lock washers provide critical vibration resistance in heavy machinery, automotive assemblies, and construction equipment where loosening under dynamic loads poses significant safety risks. The zinc-plated steel construction delivers essential corrosion protection while maintaining the Rockwell C44 hardness necessary to withstand repeated stress cycles without permanent deformation. The DIN 127B standard compliance ensures precise dimensional accuracy and reliable performance in metric fastening systems, making these washers ideal for maintenance operations, OEM manufacturing, and equipment upgrades where consistent locking action and regulatory compliance are paramount. The split design creates continuous spring tension that compensates for thermal expansion, material settling, and vibration-induced slack, effectively preventing costly downtime and maintenance interventions.
