Can anyone with the service manual for an A6 C5 2004, tell me the bolt size for attaching the fuse box (8Z0941824C) to the positive battery cable?

It is a bolt with an inset hex/allen slot.

I have looked at all of the audi diagrams and cannot find a reference.

Thanks so much in advance.

Here is the same part I believe on the A4. It is the bolt that goes into the Hex Nut.

I don't have the manual, but this tool has been pretty handy on projects related to your needs.

 

Thanks. The piece was hard to get to, but luckily the nut on top was accessible. So I got the right size bolt and guessed at the length. I was unable to find the inset Allen head but was able to use a more standard hex head.

 

It's an M6 for posterity.
