Professional Applications & Engineering Value
This spring lock washer delivers critical vibration resistance in demanding applications where loosening under dynamic loads poses significant safety risks. The 18-8 stainless steel construction provides excellent corrosion resistance for outdoor equipment, marine applications, and chemical processing facilities. The top and bottom serration design creates multiple biting surfaces that dig into both the fastener and substrate, preventing rotational movement even under extreme vibration conditions. Engineered with Rockwell C38 hardness, this washer maintains its spring properties and serration effectiveness through repeated loading cycles. The dual compatibility with both 7/8" and M22 screw sizes makes it particularly valuable for equipment manufacturers working with international standards or legacy systems, reducing inventory complexity while ensuring reliable performance across diverse applications.
Specification Summary & Compliance
This spring lock washer features precise dimensional specifications including 0.906" inner diameter, 1.299" outer diameter, and 0.059" thickness with 0.106" overall height. Manufactured from 18-8 stainless steel and hardened to Rockwell C38 for optimal performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications worldwide.
