Sourcing aluminum recessed nuts for shifters / rim calipers

[UpFromOne]

After many years of handlebar replacements, the aluminum M6 nuts for my carbon shifter clamps have worn.

I did alot of searching for these, but no results at all.
Anyone know of a source for these?
Aluminum M6 recessed nuts, any length (can always shorten them).

Thx

No one?
Have these parts disappeared? They're not just for rim brakes but shifters too.

You have a picture of your current recessed nuts?

Campagnolo has them for their shifters, and a type for their rim brakes to.
