Professional Applications & Engineering Value

This zinc-flake-coated steel wedge lock washer delivers critical vibration resistance in demanding industrial applications where fastener loosening can compromise safety and operational integrity. The dual serration technology (top and bottom) creates multiple locking points that bite into both the fastener and mating surface, effectively resisting rotational forces in heavy machinery, construction equipment, and transportation systems. The Rockwell C46 hardness ensures the serrations maintain their bite through repeated stress cycles, while the corrosion-resistant coating protects against environmental degradation. Engineered for both 7/8" and M22 fastener systems, this washer provides reliable performance in applications ranging from structural steel connections to industrial machinery assembly where vibration-induced failure is a primary concern.

Specification Summary & Compliance

This wedge lock washer features precise dimensional specifications including 0.92" ID, 1.36" OD, and thickness range of 0.120-0.140". Manufactured from high-strength steel with zinc-flake coating for superior corrosion protection, the washer achieves Rockwell C46 hardness for exceptional wear resistance. The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance for industrial applications worldwide. Designed for use with both inch (7/8") and metric (M22) fastening systems, this washer meets industrial standards for vibration-resistant locking applications.
