S-91812A454 0.26" ID x 0.53" OD Extreme-Vibration-Resistant Wedge Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance through wedge lock design that maintains clamping force under extreme conditions
• Exceptional corrosion resistance with 316 stainless steel construction for harsh environments and chemical exposure
• Maximum locking security with dual-sided serrations that bite into both mating surfaces for reliable anti-loosening
• Enhanced durability and wear resistance from case hardening to Rockwell C51 hardness
• Precise metric sizing with M6 compatibility and consistent dimensions (0.26" ID, 0.53" OD) for reliable fit
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global industrial use
• Optimized thickness range (0.070-0.090") providing consistent performance across various assembly requirements

Professional Applications & Engineering Value

This M6 wedge lock washer delivers critical engineering solutions where vibration-induced loosening compromises assembly integrity. The 316 stainless steel material provides superior corrosion resistance for marine, chemical processing, and outdoor applications, while the top and bottom serration design creates a mechanical lock that resists rotational forces. The case hardened surface treatment to Rockwell C51 ensures the serrations maintain their bite through repeated stress cycles. These metric washers are engineered for heavy machinery, transportation equipment, and structural applications where vibration resistance is paramount. The dual serration pattern distributes load evenly, preventing surface damage while maintaining consistent clamping force in high-stress environments.
