S-97913A115 0.42" ID x 0.65" OD Extreme-Vibration-Resistant Wedge Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance through wedge locking action that increases tension under load, preventing fastener loosening in high-stress environments
• Enhanced locking performance with dual-sided serrations on both top and bottom surfaces that bite into mating surfaces for maximum security
• Exceptional corrosion protection from black zinc-flake coating that provides long-lasting durability in harsh industrial conditions
• Reliable hardness rating of Rockwell C48 ensures consistent performance and resistance to deformation under heavy loads
• Precision M10 metric sizing with 0.42" ID and 0.65" OD for perfect fit with standard M10 fasteners
• Full regulatory compliance with RoHS 3 and REACH standards for safe use across global industrial applications
• Optimized thickness range of 0.090-0.110" provides ideal compression characteristics for various joint requirements

Professional Applications & Engineering Value

This M10 metric wedge lock washer delivers critical vibration resistance in demanding industrial applications where fastener security is paramount. The black zinc-flake-coated steel construction provides superior corrosion protection while maintaining the mechanical properties needed for heavy-duty use. The unique top and bottom serration design creates multiple biting surfaces that dig into both the fastener and base material, effectively preventing rotation and loosening caused by dynamic loads, machinery vibration, or thermal cycling. Engineered with Rockwell C48 hardness, this washer maintains its locking capability through repeated stress cycles without deforming. Ideal for automotive assemblies, heavy machinery, construction equipment, and industrial manufacturing where reliable vibration-resistant fastening solutions are essential for operational safety and reduced maintenance intervals.
