Professional Applications & Engineering Value
This M12 split lock washer delivers critical vibration-resistant fastening in demanding industrial environments. The curved spring design creates continuous tension that compensates for thermal expansion, material relaxation, and dynamic loads - solving common loosening issues in machinery, automotive assemblies, and electrical enclosures. Manufactured from 18-8 stainless steel, these washers provide excellent corrosion resistance while maintaining spring properties in wet, chemical, or outdoor applications. The DIN 128A standard ensures dimensional precision and reliable performance across European equipment specifications, making these metric lock washers ideal for OEM manufacturing, maintenance operations, and retrofit projects requiring certified components.
Specification Summary & Compliance
This split lock washer meets DIN 128A dimensional standards with precise 12.2mm inner diameter, 21.1mm outer diameter, 2.0mm thickness, and 3.4mm overall height. The curved spring configuration provides consistent locking force for M12 fastener applications. Manufacturing complies with international environmental regulations including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring unrestricted use in global markets. The 18-8 stainless steel material offers reliable performance without additional hardness rating requirements for general industrial applications.
