Those pictured at the top are what I have been looking for.

The Camber T tops are on my stands now but I'm not happy about not being able to tighten down the cymbals.

I really appreciate you having taken the time to try to help me.!

Regards, Jim

No Problem...................did you try Universal Percussion?

I know they used to sell those exact nuts, but just without the Sonor name.

I have something very similar to those Sonor's, except they don't squeeze. And they are also 8mm thread. If by chance you need some, let me know.
