S-93501A029 0.264" ID x 0.374" OD Heavy-Vibration-Resistant Spring Lock Washers for Socket Head Screws

Key Features & Benefits at a Glance

• Superior vibration resistance through spring lock design that maintains constant tension under dynamic loads
• Enhanced anti-loosening performance with dual top and bottom serrations that bite into both mating surfaces
• Exceptional durability provided by steel construction with Rockwell C40 hardness for long service life
• Versatile compatibility with both inch (1/4") and metric (M6) fastener systems in industrial applications
• Reliable grip and stability from precision-engineered dimensions (0.264" ID × 0.374" OD) ensuring proper fit
• Environmental compliance meeting RoHS 3 and REACH standards for safe use in regulated industries
• Optimized load distribution with 0.028" thickness and 0.047" overall height for space-constrained assemblies

Professional Applications & Engineering Value

This spring lock washer delivers critical vibration resistance in demanding industrial environments where fastener integrity is paramount. The dual serration design on both top and bottom surfaces creates multiple biting edges that aggressively resist rotational movement, making it ideal for heavy machinery, automotive assemblies, and electrical equipment subject to constant vibration. Manufactured from high-grade steel with Rockwell C40 hardness, these washers maintain their spring tension and serration effectiveness through repeated load cycles. The precise dimensional control ensures consistent performance whether used with M6 metric or 1/4 inch fasteners, providing engineers with a reliable solution for mixed-standard assemblies. This combination of mechanical locking action and material strength addresses the common failure point of vibration-induced loosening in critical connections.
