S-97913A111 0.26" ID x 0.43" OD Extreme-Vibration-Resistant Wedge Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance due to the wedge lock design that maintains consistent clamping force under dynamic loads
• Enhanced corrosion protection from the black zinc-flake coating, extending service life in harsh industrial environments
• Reliable, non-slip locking performance with dual-sided (top and bottom) serrations that bite into mating surfaces
• Exceptional durability and wear resistance provided by the high Rockwell C48 hardness steel material
• Precise fit for M6 metric screws with a 0.26" ID and 0.43" OD, ensuring easy installation and optimal load distribution
• Compliance with major environmental regulations including RoHS 3 and REACH, making them suitable for global supply chains
• Versatile thickness range (0.060-0.080") to accommodate slight variations and maintain effective spring tension

Professional Applications & Engineering Value

This M6 metric wedge lock washer is engineered to solve critical issues in high-vibration and heavy-load industrial applications. The black zinc-flake-coated steel construction provides excellent corrosion resistance, essential for outdoor machinery, automotive assemblies, and construction equipment exposed to moisture and chemicals. The unique top and bottom serration design ensures the washer bites securely into both the bolt and the workpiece, preventing loosening from shock, vibration, or thermal cycling. This makes it an ideal choice for vibration-resistant fastening in engines, conveyor systems, and structural frameworks, where failure is not an option. By maintaining clamp load, it reduces maintenance downtime and increases the reliability of the entire assembly.

Specification Summary & Compliance

This washer is manufactured to precise dimensional standards with an Inside Diameter (ID) of 0.26", Outside Diameter (OD) of 0.43", and a Thickness range of 0.060-0.080", designed specifically for M6 metric screws.
