S-91074A169 0.26" ID x 0.53" OD Extreme-Vibration-Resistant Wedge Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance prevents loosening under extreme dynamic loads, ensuring long-term joint integrity in high-stress environments.
• Dual-sided serrations on both top and bottom surfaces provide maximum bite and holding power, eliminating the need for additional locking mechanisms.
• Zinc-flake-coated steel construction offers excellent corrosion resistance, extending the washer's service life in harsh industrial conditions.
• High Rockwell C46 hardness ensures exceptional durability and resistance to deformation under high clamping forces.
• Precision M6 metric sizing with 0.26" ID and 0.53" OD guarantees perfect fit and optimal performance with standard M6 fasteners.
• Full RoHS 3 and REACH compliance meets the latest environmental regulations, making it suitable for global supply chains and sensitive applications.
• Consistent 0.090-0.110" thickness provides reliable performance and predictable clamping behavior in automated assembly processes.

Professional Applications & Engineering Value

This M6 metric wedge lock washer is engineered to solve critical vibration-induced loosening problems in demanding industrial applications. The zinc-flake-coated steel material provides robust corrosion protection, while the unique top and bottom serration design creates superior friction and bite on both contact surfaces. This dual-sided action effectively resists rotational forces and maintains clamp load in high-vibration environments such as heavy machinery, automotive assemblies, and electrical enclosures. The Rockwell C46 hardness ensures the serrations maintain their sharpness and effectiveness through multiple installation cycles, delivering reliable anti-loosening performance that reduces maintenance frequency and prevents equipment failure.
