S-93281A106 0.51" ID x 0.77" OD Extreme-Vibration-Resistant Wedge Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance with wedge lock design that maintains tightness under extreme dynamic loads
• Maximum grip and anti-loosening performance through dual-sided serrations on both top and bottom surfaces
• Exceptional durability and wear resistance thanks to Rockwell C46 hardness rating
• Long-lasting corrosion protection with zinc-flake coating on steel construction
• Precise metric sizing compatibility with M12 fasteners and 0.51" ID/0.77" OD dimensions
• Reliable performance in demanding environments including heavy machinery and high-vibration applications
• Consistent 0.130" thickness ensures uniform pressure distribution and proper joint integrity

Professional Applications & Engineering Value

This M12 spring lock washer delivers critical engineering solutions for industries where vibration-induced fastener failure poses significant risks. The zinc-flake-coated steel construction provides excellent corrosion resistance while the dual serration technology creates multiple biting edges that dig into both the fastener and mating surface, effectively preventing rotational loosening. The wedge lock mechanism combined with top and bottom serrations creates a self-locking action that becomes tighter under vibration, making it ideal for heavy machinery, automotive assemblies, construction equipment, and industrial manufacturing applications where reliability is paramount. The metric sizing ensures compatibility with international standards and global equipment specifications.
