Professional Applications & Engineering Value

This M5 wave split lock washer delivers critical vibration resistance in demanding industrial applications where fastener loosening can compromise safety and performance. The zinc-plated steel construction provides essential corrosion protection for machinery, automotive assemblies, and electrical enclosures exposed to harsh environments. Engineered to DIN 128B standards, the wave configuration maintains constant spring pressure that effectively counters vibrational forces in motors, pumps, and heavy equipment. The Rockwell C44 hardness ensures the washer withstands repeated compression cycles without permanent deformation, making it ideal for maintenance-critical applications where disassembly and reassembly are frequent. This metric lock washer solves the common industrial challenge of fastener loosening while meeting stringent environmental compliance requirements.

Specification Summary & Compliance

This precision split lock washer features 5.1mm inner diameter and 9.2mm outer diameter with 0.9mm thickness, manufactured to DIN 128B dimensional and performance standards. The wave-type design provides consistent spring action while the zinc-plated steel material offers both strength and corrosion resistance. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and suitability for global industrial applications requiring restricted substance compliance.
