Professional Applications & Engineering Value
This 316 stainless steel wedge lock washer delivers critical vibration resistance in demanding industrial environments where fastener loosening can compromise safety and equipment integrity. The top and bottom serrations create a mechanical locking action that prevents rotational movement, while the case hardened surface maintains serration sharpness through repeated use cycles. Engineered for heavy-duty applications including machinery, transportation equipment, and structural assemblies, this washer provides reliable performance in corrosive environments where carbon steel components would fail. The dual inch and metric compatibility (9/16" and M14) makes it ideal for multinational operations and equipment with mixed fastener systems.
Specification Summary & Compliance
This wedge lock washer features precise dimensions of 0.6" ID x 1.21" OD with thickness ranging 0.120-0.140". The case hardened treatment achieves Rockwell C51 hardness for optimal wear resistance. Manufactured to industrial standards for locking washers, this component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance for industrial procurement.
