S-91812A727 0.92" ID x 1.36" OD Extreme-Vibration-Resistant Wedge Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance through dual-sided serration technology that bites into both mating surfaces, preventing loosening under extreme dynamic loads
• Exceptional corrosion resistance with 316 stainless steel construction, ideal for harsh chemical, marine, and outdoor environments
• Enhanced durability and wear resistance from case hardening to Rockwell C51 hardness, maintaining locking performance through repeated use
• Dual measurement system compatibility accommodating both 7/8" (inch) and M22 (metric) screw sizes for global project flexibility
• Reliable performance in demanding applications with precise dimensional control (0.92" ID, 1.36" OD) ensuring proper fit and function
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries
• Optimized load distribution through wedge-lock design that increases clamping force as vibration intensifies

Professional Applications & Engineering Value

This 316 stainless steel wedge lock washer delivers critical vibration-resistant performance in demanding industrial applications where fastener integrity is paramount. The top and bottom serration design creates multiple biting points that actively resist rotational loosening caused by machinery vibration, thermal cycling, and dynamic loading conditions. Engineered with case hardened 316 stainless steel, these washers maintain their locking capability in corrosive environments that would degrade standard carbon steel alternatives. The dual compatibility with both 7/8" and M22 screw sizes makes them ideal for equipment manufacturing, marine installations, chemical processing facilities, and infrastructure projects requiring reliable, long-term fastening solutions that withstand environmental challenges while meeting international regulatory standards.

Specification Summary & Compliance

This wedge lock washer features precise dimensional specifications including 0.92" inner diameter, 1.36" outer diameter, and 0.120-0.140" thickness range. Manufactured from 316 stainless steel and case hardened to achieve Rockwell C51 hardness, the washer incorporates dual serrations on both top and bottom surfaces. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use across regulated industries and international markets.
