Professional Applications & Engineering Value
This M2.5 split lock washer delivers critical engineering value through its Black-Oxide 18-8 Stainless Steel construction, specifically engineered to combat vibration-induced loosening in precision assemblies. The split lock design creates continuous spring tension that maintains clamping force despite thermal cycling and mechanical stress. The Black-Oxide surface treatment enhances corrosion resistance while reducing galling during installation, making it ideal for metric fastening applications in electronics, automotive subsystems, and precision machinery where vibration resistance is paramount. The DIN 127B standard ensures dimensional consistency for reliable performance in high-cycle manufacturing environments.
Specification Summary & Compliance
Manufactured to DIN 127B specifications with precise metric dimensions: 2.9mm ID, 5.1mm OD, and 0.5-0.7mm thickness range. Constructed from 18-8 Stainless Steel with Black-Oxide finish for enhanced durability. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance. Designed specifically for M2.5 screw applications in industrial and commercial settings.
