S-91812A744 0.92" ID x 1.65" OD Extreme-Vibration-Resistant Wedge Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance through dual top and bottom serrations that bite into mating surfaces, preventing loosening under extreme dynamic loads
• Exceptional corrosion resistance with 316 stainless steel construction, ideal for harsh environments including marine and chemical processing applications
• Enhanced durability and wear resistance from case hardening to Rockwell C51 hardness, maintaining locking performance through repeated use cycles
• Dual system compatibility designed for both 7/8" inch and M22 metric screw sizes, providing flexibility for global equipment specifications
• Reliable locking performance with wedge-lock design that creates constant tension, eliminating the need for additional locking mechanisms
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries worldwide
• Precise dimensional control with 0.92" ID and 1.65" OD specifications ensuring proper fit and optimal load distribution

Professional Applications & Engineering Value

This 316 stainless steel wedge lock washer delivers critical engineering solutions for industries where vibration-induced fastener failure poses significant safety and maintenance challenges. The dual serration technology (top and bottom) creates multiple biting surfaces that mechanically resist rotational forces, making it ideal for heavy machinery, transportation equipment, and structural applications. The case hardened surface reaching Rockwell C51 ensures the serrations maintain their sharpness through multiple installation cycles, while the 316 stainless steel material provides exceptional resistance to saltwater, chemicals, and extreme temperatures. This combination addresses the common industrial pain points of maintenance frequency, equipment downtime, and safety compliance in demanding environments where reliable vibration resistance is non-negotiable.

Specification Summary & Compliance

Manufactured to precise dimensional specifications including 0.92" inner diameter, 1.65" outer diameter, and 0.120-0.140" thickness range. Designed specifically for 7/8" and M22 screw applications with dual serrations on both top and bottom surfaces. The washer undergoes case hardening treatment to achieve Rockwell C51 hardness for optimal durability. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use across global markets and regulated industries.
