Professional Applications & Engineering Value
This M27 metric spring lock washer delivers critical engineering value in industrial applications where vibration-induced fastener failure poses significant risks. The dual-sided serration technology creates multiple biting edges that dig into both the fastener head and mounting surface, effectively resisting rotational forces that cause loosening. Made from high-grade steel with Rockwell C40 hardness, this washer maintains its spring tension and locking capability even under extreme cyclic loading conditions. The metric spring lock washer is particularly valuable in heavy machinery, automotive assemblies, and structural applications where maintaining bolt preload is essential for safety and operational integrity. The combination of precise dimensional control and top and bottom serration ensures consistent performance across varying surface materials and conditions.
Specification Summary & Compliance
This metric spring lock washer features precise dimensional specifications including 1.126" internal diameter, 1.535" external diameter, 0.071" thickness, and 0.122" overall height, engineered for M27 fastener applications. The washer maintains Rockwell C40 hardness for consistent performance and meets international compliance standards including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance for industrial fastener applications.
