Professional Applications & Engineering Value
This M6 wedge lock washer delivers critical vibration resistance in demanding applications where joint integrity is paramount. The 316 stainless steel construction provides exceptional corrosion resistance for marine, chemical processing, and outdoor equipment applications. The top and bottom serrated design creates multiple biting edges that prevent rotational loosening under cyclic loading conditions. With case hardening to Rockwell C51, these washers maintain their locking capability through repeated disassembly and reassembly cycles. The metric system compatibility ensures seamless integration with European machinery and equipment specifications, making them ideal for automotive assembly, heavy machinery, and precision manufacturing applications where vibration-induced failure is not an option.
Specification Summary & Compliance
Manufactured to precise dimensional standards with 0.26" internal diameter and 0.43" outer diameter, this wedge lock washer features controlled thickness between 0.080-0.100" for consistent performance. The case hardened treatment achieves Rockwell C51 hardness for superior durability. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets. Designed specifically for M6 screw sizes in metric measurement systems.
