S-90127A035 0.646" ID x 1.273" OD Heavy-Vibration-Resistant Spring Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance through spring lock design that maintains consistent tension under dynamic loads
• Enhanced grip and anti-loosening performance with top serration pattern that bites into mating surfaces
• Exceptional durability and wear resistance provided by Rockwell C40 hardened steel construction
• Precise fit for 5/8" fasteners with 0.646" ID and 1.273" OD dimensions ensuring proper installation
• Reliable performance in demanding environments with controlled thickness (0.095-0.101") for consistent compression
• Compliance with global environmental standards including RoHS 3 and REACH for international industrial applications
• Optimized for inch-system applications with standardized dimensions for seamless integration in existing assemblies

Professional Applications & Engineering Value

This 5/8" spring lock washer delivers critical engineering solutions for industrial applications where vibration-induced loosening compromises safety and performance. The top serration design creates mechanical interference that prevents rotational slip, while the spring steel construction maintains constant preload even under thermal cycling and dynamic stresses. With Rockwell C40 hardness, these steel washers withstand repeated compression cycles without deformation, making them ideal for heavy machinery, automotive assemblies, and construction equipment. The precise dimensional control ensures consistent performance in inch-system applications, providing reliable fastening in high-vibration environments where standard flat washers would fail.

Specification Summary & Compliance

This spring lock washer features precise dimensional specifications including 0.646" ID, 1.273" OD, and thickness range of 0.095-0.101" with overall height of 0.156". Manufactured to inch system standards for 5/8" screw applications, the washer maintains Rockwell C40 hardness for consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental standards for industrial components while ensuring reliable fastening performance in demanding applications.
