These Hillman 3/8 in.-24 TPI Nylon Insert Stop Nuts are ideal for securely fastening a bolt when connecting materials. The nylon ring inside the nut creates rotational resistance when displaced by a mating male threaded fastener, thus preventing loosening. Use with bolts or washers of the same thread size and finish.

  • HIGH-QUALITY HEX NUT DESIGN: Used for fastening to a bolt when mechanically joining materials
  • CONSTRUCTED WITH A NYLON INSERT: The insert offers additional security to keep nut in place
  • PART OF A COMPLETE FASTENING SOLUTION: Use with bolts or washers of the same thread size and finish
  • 3/8"-24 SAE FINE THREAD: Matches bolts or rods of a 3/8"-24 fine thread size
