Professional Applications & Engineering Value
This M30 metric split lock washer addresses critical vibration-induced loosening in heavy machinery, construction equipment, and industrial assemblies. The zinc-plated steel construction combined with Rockwell C44 hardness creates a durable barrier against corrosion while maintaining spring tension under continuous stress. Engineered to DIN 7980 standards, these washers provide reliable performance in automotive, manufacturing, and structural applications where vibration resistance is paramount. The split lock design creates constant upward force on the fastener, compensating for material relaxation and thermal expansion, making it ideal for heavy-duty industrial applications requiring long-term fastener security.
Specification Summary & Compliance
Manufactured to DIN 7980 specifications with precise dimensional tolerances: 31.7mm inner diameter, 44.1mm outer diameter, and 5.8-6.2mm thickness range. The standard split lock washer type ensures consistent performance across M30 fastener applications. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting international standards for industrial components. The Rockwell C44 hardness rating confirms material integrity and mechanical performance for demanding applications.
