Worked great, and dimensions provided are accurate. I needed them for a small replacement knob and they work great. Now I have 11 extra in case I lose one again...

I like this hard to find knurled knobs. I use them for kydek cheek riser, rather than the big plastic/alum. knobs that come with the kit. cheaper by the dozen! I know, you only get 10 in a pack.

Use them on my fishing rod building jig for adjustable wheels. These nuts are small enough to keep out of the way of rods riding on 1" bearing wheels yet they allow fine adjusting for different diameter rods. Work very well for my application.
