Metric (turned nuts?) nuts info

[bowewilson]

I am trying to track down various size metric nuts for my R57 bike.
Not sure what they are called, they look like a castellated nut without the slots, photo attached.
Any idea where I can get them?

When I was still in business, (before I sold Bench Mark Works) I kept them in stock.
Max BMW has all of my stock.
Go to benchmarkworks.com the site is still active. When it opens, click on Prewar in the left hand column, and you will find the following



P10 08 3 -- $2.30 nut stepped polished ss SW10 6x.85 R12-R17

Google "step nuts" and look at the images. See if you can find something in your neck of the woods.

Well, Mark Hugggett, (bmwbike.com) in Switzerland has them and will ship to you.
When I listed them, I added a prefix P to the number because they would then show up in my segregated PREWAR list of parts.
The true part numbers is below for what is available
