S-93281A105 0.42" ID x 0.65" OD Extreme-Vibration-Resistant Wedge Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance with dual-sided serrations that bite into mating surfaces, preventing loosening under dynamic loads
• Enhanced corrosion protection from zinc-flake coating, extending service life in harsh industrial environments
• Exceptional durability with Rockwell C46 hardness, maintaining locking performance under high-stress conditions
• Precise metric sizing with 0.42" ID and 0.65" OD for perfect compatibility with M10 fasteners
• Reliable wedge lock action that creates consistent spring tension for secure fastening in critical applications
• Versatile top and bottom serration design ensuring optimal performance regardless of installation orientation
• Consistent thickness control between 0.100-0.110" for uniform compression and reliable sealing performance

Professional Applications & Engineering Value

This M10 spring lock washer delivers critical engineering solutions where vibration-induced fastener failure is a major concern. The zinc-flake-coated steel construction provides exceptional corrosion resistance while maintaining the mechanical properties needed for demanding environments. The unique wedge lock system with dual serrations creates a mechanical interference that actively resists rotational forces, making it ideal for automotive assemblies, heavy machinery, and construction equipment where constant motion and impact loads are present. The metric dimensions ensure seamless integration with international equipment standards, while the controlled thickness provides consistent spring action that compensates for thermal expansion and material relaxation over time.

Specification Summary & Compliance

This spring lock washer features precise metric dimensions with 0.42" internal diameter and 0.65" outer diameter, specifically designed for M10 screw applications. The washer maintains tight thickness tolerance between 0.100-0.110" and achieves Rockwell C46 hardness for consistent performance. Manufactured to meet international metric standards with dual serration technology for maximum vibration resistance. The zinc-flake coating provides superior corrosion protection while complying with RoHS and REACH environmental standards for industrial applications.
