Professional Applications & Engineering Value
This M12 metric spring lock washer delivers critical vibration damping for demanding industrial applications where fastener security is paramount. The top and bottom serrations bite into both mating surfaces, creating mechanical interference that resists rotational loosening caused by machinery vibration, thermal cycling, or dynamic loads. Manufactured from hardened steel with Rockwell C40 hardness, these washers maintain their spring tension and serration sharpness through repeated compression cycles. Ideal for automotive assemblies, heavy equipment, and precision machinery, this steel spring washer provides reliable locking performance where standard flat washers fail, reducing maintenance downtime and preventing equipment damage from loose fasteners.
Specification Summary & Compliance
This spring lock washer features precision dimensions (0.512" ID × 0.709" OD × 0.039" thickness) compatible with M12 metric fasteners. Manufactured to industrial standards with top and bottom serrations for maximum locking effectiveness. The steel construction achieves Rockwell C40 hardness for optimal spring performance and durability. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance for industrial applications.
