S-97913A124 0.34" ID x 0.65" OD Extreme-Vibration-Resistant Wedge Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance through dual-sided serrations that bite into mating surfaces, preventing loosening under dynamic loads
• Enhanced corrosion protection with black zinc-flake coating that provides excellent environmental durability in industrial settings
• Exceptional hardness at Rockwell C48 ensures minimal deformation and maintains locking performance under high clamping forces
• Precise M8 compatibility with 0.34" ID and 0.65" OD dimensions for perfect fitment in metric fastener systems
• Double-sided engagement with top and bottom serrations creates maximum friction against both bolt head and workpiece surfaces
• Consistent thickness control between 0.090-0.110" ensures reliable performance and uniform clamping pressure distribution
• Environmental compliance meeting RoHS 3 and REACH standards for safe use in regulated industries worldwide

Professional Applications & Engineering Value

This M8 metric wedge lock washer delivers critical vibration resistance in demanding industrial environments where fastener loosening can compromise safety and equipment integrity. The black zinc-flake-coated steel construction provides superior corrosion protection while maintaining the structural strength needed for heavy-duty applications. Dual serrations on both top and bottom surfaces create a powerful locking mechanism that bites into mating components, effectively resisting rotational forces in machinery, automotive assemblies, and structural frameworks. The Rockwell C48 hardness ensures the serrations maintain their bite without deforming under extreme pressure, making these wedge lock washers ideal for high-vibration equipment, transportation systems, and industrial machinery where reliable fastener security is non-negotiable.

Specification Summary & Compliance

This metric wedge lock washer features precise dimensional specifications with 0.34" inner diameter for M8 screw compatibility and 0.65" outer diameter for optimal load distribution. The controlled thickness range of 0.090-0.110" ensures consistent performance across production batches. Manufactured from high-grade steel with black zinc-flake coating for corrosion resistance, these washers meet international environmental standards including RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance with the latest SVHC requirements as of January 2023.
