Description

Hex Flange Lock Nut, Serrated, Grade 8 Steel, Zinc Yellow, 5/16-18 combines high strength with vibration resistance for secure, long-lasting fixtures. Made from Grade 8 steel and finished with a yellow zinc coating, these nuts are built to withstand demanding industrial environments while resisting corrosion.

The unique hex flange design distributes clamping load over a larger surface area, reducing pull-through, while the integrated serrations bite into the mating surface to prevent loosening under dynamic loads. This makes them ideal for automotive, machinery, and construction applications where reliability is critical.

  • Thread size: 5/16-18 UNC
  • Material: Grade 8 steel
  • Finish: Zinc yellow plating
  • Type: Hex flange lock nut with serrated flange
  • Anti-loosening design: Serrated flange grip

Ideal for high-strength assemblies that require secure, vibration-resistant fasteners. Pair with compatible bolts and mounting surfaces for best results.
