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.

I like that the knurled part was a bit larger than others I’ve purchased in the past. For a small screw I could actually get my fingers on them to tighten

Great finish on all surfaces, no thread burrs or sharp edges, very high quality, solid brass. It’s really a lot of quality machining for this price. Highly recommended.

Worked great for my blasting cabinet glass hold down. Fits 8-32 screws perfectly and look pretty flawless

These are exactly as described - Round knurled thumb nuts that fit an 8-32 screw. They are made of solid brass. I bought them to use for antique looking electrical contacts to attach wires to an 8-32 screw. They seem to be good quality. There is just something about using solid brass hardware that I like.

The threads had been cut with a dull tap. Not full cut all the way through. I had to re-tap them all.
