Key Features & Benefits at a Glance
- Superior vibration resistance with dual top and bottom serrations that bite into mating surfaces, preventing loosening under dynamic loads
- Exceptional durability from Rockwell C40 hardened steel construction, resisting deformation and maintaining locking force in high-stress applications
- Broad compatibility with both inch (1 3/8") and metric (M36) screw systems, simplifying inventory for global operations
- Precise dimensional fit with 1.496" ID and 2.126" OD ensuring proper alignment and uniform load distribution
- Reliable performance in demanding environments thanks to robust 0.098" thickness and 0.165" overall height
- Regulatory compliance with RoHS 3 and REACH standards, ensuring safe use across international markets
- Reduced maintenance cycles through consistent locking action that minimizes fastener retightening needs
Professional Applications & Engineering Value
This spring lock washer delivers critical vibration-dampening performance for heavy machinery, construction equipment, and automotive assemblies where M36 fasteners experience constant dynamic stress. The steel construction with Rockwell C40 hardness ensures the dual serration pattern maintains biting action without flattening, solving common loosening issues in high-vibration environments. Engineered with precise 1.496" ID and 2.126" OD dimensions, it provides secure seating on 1 3/8" screw applications while the top and bottom serration creates superior friction locking between components. This design prevents costly downtime in industrial settings by maintaining joint integrity in vibrating systems, making it ideal for mining equipment, agricultural machinery, and structural steel connections.
