These Hillman M8-1.25 Metric 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
  • M8-1.25 METRIC COARSE THREAD: Matches bolts or rods of an M8-1.25 coarse thread size
