S-90895A114 1.063" ID x 1.496" OD Heavy-Vibration-Resistant Spring Lock Washers for Socket Head Screws

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
• Excellent corrosion resistance from 18-8 stainless steel construction, ideal for harsh industrial environments and outdoor applications
• Enhanced durability and load distribution thanks to Rockwell C38 hardness, maintaining performance under high-stress conditions
• Versatile compatibility with both inch (1") and metric (M25) screw systems, reducing inventory complexity for global operations
• Reliable locking performance through spring lock design that maintains constant tension, minimizing maintenance needs
• Environmental compliance assurance with RoHS 3 and REACH standards, meeting international regulatory requirements
• Optimized dimensional precision with 1.063" ID and 1.496" OD ensuring proper fit and consistent performance across applications

Professional Applications & Engineering Value

This spring lock washer delivers critical engineering solutions for applications where vibration-induced fastener failure poses significant risks. The 18-8 stainless steel construction provides inherent corrosion resistance for demanding environments including marine, chemical processing, and outdoor infrastructure. The innovative dual serration design (top and bottom) creates multiple biting surfaces that significantly enhance grip compared to single-serration alternatives, making it ideal for heavy machinery, automotive assemblies, and structural applications. The Rockwell C38 hardness ensures the washer maintains its spring properties and locking force even after repeated loading cycles, while the precise 1.063" ID and 1.496" OD dimensions guarantee proper seating on both 1" screw and M25 fastener systems. This combination of material strength and intelligent design addresses common industrial challenges of joint integrity, maintenance frequency, and component longevity.
