Professional Applications & Engineering Value
This M18 wedge lock washer is engineered to solve critical issues in heavy-duty industrial applications where vibration and corrosion lead to fastener failure. Constructed from 316 stainless steel, it offers excellent resistance to corrosive elements, making it suitable for marine, chemical processing, and outdoor machinery. The dual serration technology on both top and bottom surfaces ensures a firm grip, effectively resisting loosening caused by constant motion or shock loads. By utilizing a case hardened process and achieving Rockwell C51 hardness, this washer maintains its locking force and structural integrity over time, reducing maintenance needs and downtime in demanding settings like construction, transportation, and manufacturing equipment.
Specification Summary & Compliance
This metric wedge lock washer features precise dimensions with an ID of 0.77", OD of 1.36", and thickness of 0.120-0.140", designed for M18 screw sizes. It is manufactured to high standards with top and bottom serrations for optimal performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets strict environmental and safety requirements for industrial use.
