Professional Applications & Engineering Value
Engineered for demanding industrial applications, these M6 split lock washers address critical challenges in machinery assembly, automotive systems, and electrical enclosures where vibration-induced loosening can lead to equipment failure. The 18-8 stainless steel construction provides inherent corrosion resistance, making them suitable for outdoor or chemically exposed environments. The split lock washer type creates continuous tension that compensates for thermal expansion and dynamic loads, while compliance with DIN 7980 ensures interchangeability and reliability in European machinery designs. Their metric dimensions (6.5mm ID, 9.9mm OD) facilitate precise integration with M6 screw assemblies, delivering consistent anti-vibration performance that reduces maintenance frequency and enhances operational safety.
Specification Summary & Compliance
This split lock washer features precise metric dimensions: 6.5mm internal diameter, 9.9mm outer diameter, and 1.5-1.7mm thickness specifically designed for M6 screw size applications. Manufactured to DIN 7980 specifications for dimensional accuracy and performance consistency. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial use across global markets.
