Professional Applications & Engineering Value
These wedge lock washers are engineered to solve critical vibration-induced loosening problems in heavy-duty industrial applications. The black zinc-flake-coated steel construction provides exceptional corrosion resistance while maintaining Rockwell C48 hardness for durability under extreme conditions. The top and bottom serrated surfaces create mechanical interference that prevents rotation and backing out, making them ideal for machinery, construction equipment, automotive assemblies, and structural applications where reliable vibration resistance is paramount. Available in both inch (5/8") and metric (M16) sizing, these washers offer flexibility across international engineering specifications while maintaining consistent locking performance through precise dimensional control and material integrity.
Specification Summary & Compliance
This wedge lock washer features precise dimensional specifications including 0.67" ID, 1" OD, and 0.120-0.140" thickness range. Manufactured from steel with black zinc-flake coating and hardened to Rockwell C48 for optimal performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use in global industrial applications. Designed to accommodate both 5/8" and M16 fastener sizes with dual-sided serrations for maximum locking effectiveness in vibration-prone environments.
