Key Features & Benefits at a Glance
- Superior vibration resistance through spring lock design, preventing fastener loosening in high-stress environments.
- Enhanced grip and stability with dual serration on top and bottom surfaces, ensuring secure locking on both mating surfaces.
- High durability and wear resistance from Rockwell C40 hardened steel construction, extending service life in demanding applications.
- Precise fit for M20 screws with 0.827" ID and 1.181" OD, providing reliable performance in metric fastener assemblies.
- Compliance with environmental regulations including RoHS 3 and REACH, ensuring safe use in global industrial markets.
- Consistent performance under load due to controlled thickness (0.059") and overall height (0.098"), maintaining locking force integrity.
Professional Applications & Engineering Value
This M20 metric spring lock washer is engineered to address critical vibration-induced failures in industrial machinery, automotive systems, and heavy equipment. The top and bottom serration design bites into both the fastener and surface, creating a mechanical lock that resists rotational forces and shock loads. Made from Rockwell C40 hardened steel, it withstands repetitive stress without deforming, making it ideal for high-torque applications like engine mounts, conveyor systems, and structural frameworks. Its metric sizing ensures compatibility with standard M20 fasteners, while the spring action maintains constant tension, reducing maintenance downtime and enhancing operational safety in vibration-prone environments.
Specification Summary & Compliance
This washer meets precise dimensional standards with an ID of 0.827", OD of 1.181", thickness of 0.059", and overall height of 0.098", designed for M20 screw sizes. Manufactured from steel with Rockwell C40 hardness, it ensures consistent performance under mechanical stress. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, adhering to environmental and safety requirements for industrial components.
