These Hillman 1/2 in.-20 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.

Looking for more information on nuts, bolts and washers? Check out our guide on fasteners in the product documents section.

  • 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
  • 1/2"-20 SAE FINE THREAD: Matches bolts or rods of a 1/2"-20 fine thread size
