Serrated Large Flange Free-Spinning Locknut - The bearing surface of the flange has serrations which displace material on the mating surface when the nut is wrenched into place, forming a connection that resists loosening.

  • Hex nut with a circular base flaring out from the bottom of the nut that is 6% to 25% wider than the flange of a standard serrated flange nut
  • Offers the same advantages of the standard serrated flange lock nut, including reusability, but will span even larger holes.
  • Also has a more uniform bearing-stress to clamp-force ratio than the standard serrated flange nut.
  • Thread Diameter-Pitch: 5/16"-18 inches
  • Number of Nuts per Carton: 200
