Professional Applications & Engineering Value
This spring lock washer delivers critical vibration-dampening performance for industrial machinery, automotive assemblies, and heavy equipment applications. The zinc-plated steel construction provides essential corrosion resistance while maintaining the spring tension needed for long-term fastener security. The top serration design bites into mating surfaces to prevent rotational movement, solving common loosening issues in high-vibration environments. With precise 0.402" ID dimensions and Rockwell C40 hardness, this washer maintains consistent spring force and load distribution, making it ideal for critical joints in construction equipment, manufacturing machinery, and transportation systems where vibration-induced failure is a primary concern.
