• Corrosion-resistant 316 stainless steel construction ensures longevity in harsh environments
• Curved spring design provides maximum tension and consistent load distribution
• Precision M8 metric sizing (8.4mm ID, 15mm OD) guarantees perfect fit with standard fasteners
• DIN 137A certification verifies manufacturing consistency and dimensional accuracy
• Environmental compliance with RoHS 3 and REACH standards for safe industrial use
• Compact 3.4mm overall height enables installation in space-constrained assemblies

Professional Applications & Engineering Value

This M8 spring lock washer delivers critical vibration-dampening performance for industrial machinery, automotive assemblies, and marine equipment where constant motion threatens joint integrity. The 316 stainless steel material provides exceptional chloride resistance, making it ideal for chemical processing, coastal installations, and food-grade applications. The curved DIN 137A design creates continuous spring tension that compensates for thermal expansion and material relaxation, preventing loosening under dynamic loads. Unlike flat washers, this metric spring washer actively maintains preload in bolted connections, reducing maintenance frequency and preventing equipment downtime in critical industrial washers applications.

Specification Summary & Compliance

Manufactured to DIN 137A specifications with precise dimensions (8.4mm ID × 15mm OD × 0.5mm thickness). The 316 stainless steel spring lock washer maintains dimensional accuracy per metric standards for M8 screw applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and chemical restriction adherence for global industrial supply chains.
