Any m6 thread bolt of about 10mm will do, it’s nothing special, the cylinder is held in the backplate and the bolt just stops it from falling out.

Did somebody say uzi 10 millimeter?

Edit
Replaced the glide clips on my rear drums last week along with the wheel cylinders.
The bolt was fairly sturdy find a 10.9 hardness if possible.

I want to order them from vw because they cost the same as any other stainless but they come with that green anti corrosion coating which should last for another 20 years. 😂

Btw vw use the same bolt on Bentley V12 engine.

I don't think they do come with the green coating these days. I can't say for certain but components I've bought recently look like they are hot dipped in zinc, whatever it is it isn't a great long lasting finish.
Stainless is fine in iron cylinders and lasts forever, if you have aluminium cylinders zinc plated steel would be better but the heads will rust unless greased.
Could you let us know please what Audi supply? Thanks.
 
That's strange when I was swapping wishbones and strut bearings on both of my cars, I ordered new bolts from vw not audi around 20 bolts and nuts in total and they all came with that green coating. I could be lucky and It might be just some old stock.

If you are getting the green finish that is great. The last bolts I ordered from Audi came in a flat grey finish.
