Professional Applications & Engineering Value
This wedge lock washer is engineered to solve critical vibration-induced loosening in heavy machinery, construction equipment, and transportation systems. The zinc-flake-coated steel construction provides excellent corrosion resistance in outdoor or chemically aggressive environments, while the dual top and bottom serration creates multiple biting surfaces that prevent rotational slip under dynamic loads. With Rockwell C46 hardness, it maintains locking performance in high-torque applications where standard washers would deform. The dual inch and metric compatibility (1 1/8" and M30) makes it ideal for global equipment manufacturing and maintenance operations requiring reliable vibration-resistant fastening solutions.
Specification Summary & Compliance
This washer features precise dimensional specifications with 1.24" ID, 1.85" OD, and thickness ranging 0.220-0.240". Manufactured from zinc-flake-coated steel with Rockwell C46 hardness, it meets industrial standards for locking washers. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications worldwide.
