Can anyone help me identify this stem binder nut This nut (pictured) fits the binder bolt from a vintage 3ttt stem. I would like to know the name of this nut, or the type of nut this is so that I can try to buy more.




So far, I've found similar things when searching the internet with keywords like "knurled", "conical", and "tapered", but haven't managed to find anything that has the flange.

Can anyone help?

Edit: For clarification, here's a pic of the nut in situ
I've found something similar (only the other way round) for Cinelli:
