Professional Applications & Engineering Value
This heavy-duty wedge lock washer delivers exceptional vibration resistance in demanding industrial applications where fastener security is critical. The dual serration design on both top and bottom surfaces creates multiple biting edges that dig into mating surfaces, effectively preventing rotation and loosening under extreme vibration conditions. Manufactured from black zinc-flake-coated steel with Rockwell C48 hardness, these washers maintain their locking capability through repeated stress cycles while providing superior corrosion protection. Ideal for heavy machinery, construction equipment, transportation systems, and industrial assembly lines, this wedge lock washer ensures reliable fastener performance in the most challenging environments where safety and equipment integrity cannot be compromised.
Specification Summary & Compliance
This wedge lock washer features precise inch system dimensions with 1.1" inner diameter, 1.54" outer diameter, and thickness ranging from 0.120" to 0.140" for optimal performance with 1" screw sizes. The washer's dual serration configuration on both top and bottom surfaces ensures maximum locking effectiveness. Manufactured to industrial standards using black zinc-flake-coated steel with Rockwell C48 hardness for consistent performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety requirements for industrial components.
