• Compliance with RoHS 3 and REACH regulations guarantees environmental safety and unrestricted use in global markets.
• Optimized metric dimensions (6.4mm ID, 11mm OD) ensure perfect fit and ease of installation with standard M6 fasteners.
• Compact 2.2mm overall height allows for efficient use in space-constrained assemblies without compromising performance.

Professional Applications & Engineering Value

This M6 spring lock washer is engineered to solve critical challenges in industrial fastening applications where vibration-induced loosening is a primary concern. The curved spring washer design, manufactured from zinc-plated steel, creates a continuous spring force that compensates for relaxation and thermal cycling in bolted joints. This makes it ideal for machinery, automotive assemblies, and electrical enclosures where maintaining clamp load is essential for safety and performance. The Rockwell C42 hardness ensures the washer can withstand repeated compression cycles without losing its resilience, providing a reliable, vibration-resistant locking solution that reduces maintenance needs and prevents costly downtime in heavy-duty applications.

Specification Summary & Compliance

This washer conforms to the dimensional and performance requirements of the DIN 137A standard, ensuring precise fit for M6 screw sizes with an internal diameter of 6.4mm and external diameter of 11mm. The manufacturing process adheres to strict quality controls for material and hardness (Rockwell C42). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its adherence to environmental and safety standards for hazardous substances.
