S-97913A129 0.67" ID x 1.21" 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 dynamic loads
• Enhanced locking security with dual-sided serrations on both top and bottom surfaces for maximum grip
• Exceptional durability provided by Rockwell C48 hardened steel construction that resists deformation
• Reliable corrosion protection from black zinc-flake coating that withstands harsh industrial environments
• Precise metric sizing (M16) ensures perfect fit and optimal performance in metric fastener systems
• Consistent performance guaranteed by controlled thickness range (0.120-0.140") for uniform clamping pressure
• Environmental compliance with RoHS 3 and REACH standards for safe use in regulated industries

Professional Applications & Engineering Value

This M16 metric wedge lock washer delivers critical vibration resistance in demanding industrial applications where traditional fasteners fail. The black zinc-flake-coated steel construction provides superior corrosion protection while maintaining the structural integrity needed for heavy machinery, automotive assemblies, and construction equipment. The innovative top and bottom serration design creates multiple locking points that prevent loosening under continuous vibration and thermal cycling. Engineered with Rockwell C48 hardness, this washer maintains its locking force without embedding into mating surfaces, solving common issues of joint relaxation in high-vibration environments. The precise metric dimensions ensure seamless integration with M16 fastener systems, making it an essential component for maintenance professionals and OEM engineers seeking reliable vibration-resistant solutions.
