S-91812A214 0.6" ID x 0.91" OD Extreme-Vibration-Resistant Wedge Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance through wedge lock design that maintains tension under dynamic loads
• Enhanced corrosion protection with 316 stainless steel construction for harsh industrial environments
• Maximum locking security with dual-sided serrations (top and bottom) that bite into both mating surfaces
• Exceptional durability from case hardened treatment achieving Rockwell C51 hardness
• Universal compatibility with both inch (9/16") and metric (M14) fastener systems
• Reliable performance in critical applications with precise dimensions (0.6" ID, 0.91" OD)
• Environmental compliance meeting RoHS 3 and REACH standards for global industrial use

Professional Applications & Engineering Value

Our 316 stainless steel wedge lock washers deliver exceptional engineering value in demanding industrial settings where vibration-induced loosening poses significant safety and maintenance challenges. The dual serration design (top and bottom) creates multiple biting surfaces that resist rotational movement more effectively than standard washers, while the case hardened construction ensures the serrations maintain their sharp edges through repeated stress cycles. The 316 stainless steel material provides superior corrosion resistance in chemical processing, marine, and outdoor applications, making these wedge lock washers ideal for heavy machinery, structural assemblies, transportation equipment, and processing systems where reliability cannot be compromised. The combination of inch and metric compatibility (9/16" and M14) offers flexibility for global equipment manufacturing and maintenance operations.

Specification Summary & Compliance

These wedge lock washers feature precise dimensional specifications including 0.6" inner diameter, 0.91" outer diameter, and 0.110-0.130" thickness range, engineered to exacting standards for consistent performance. The case hardened treatment achieves Rockwell C51 hardness for optimal wear resistance, while the dual serration pattern (top and bottom) ensures maximum locking capability. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards guarantees these components meet the strictest international regulatory requirements for industrial applications.
