About this item

  • A knurled nut is a nut with a knurled outside surface, rather than hex.
  • This makes them easy to tighten by hand, as well as adding a decorative finish.
  • The knurled portion adds friction for extra grip when tightening
  • Knurled Thumb Nuts are used in finished materials, such as light fixtures, antique cars and motorcycles.
  • Knurled Thumb Nuts are available in both Coarse (UNC) and Fine (UNF) thread sizes.

These knurled nuts were the perfect item for a project I've been working on. I needed to construct a special, adjustable drafting curve for long, gradual curved lines. These nuts were the last item I needed to finish my new drafting tool. And I got them in record time. Thanks for your help.
