Professional Applications & Engineering Value
This steel spring lock washer is engineered to solve critical vibration-induced loosening problems in industrial machinery, automotive assemblies, and heavy equipment. The top serration location creates aggressive biting action that maintains clamp force under dynamic loads, while the spring lock design provides constant tension to compensate for material settling and thermal expansion. Manufactured to precise inch system measurements, this washer delivers reliable performance in 3/8" screw size applications where vibration resistance is paramount. The combination of steel material and Rockwell C40 hardness ensures the washer maintains its spring properties without fracturing under repeated compression cycles, making it ideal for maintenance-critical environments where fastener failure is not an option.
Specification Summary & Compliance
This spring lock washer features precise dimensional specifications including 0.402" ID, 0.877" OD, 0.059-0.065" thickness, and 0.108" overall height, engineered for 3/8" screw size applications. The washer meets industry standards for Rockwell C40 hardness and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial use across global markets.
