Hey everyone,

I need a new set of OEM or equivalent wheel bolts for a 2002 A4, as I lost the entire lot when I moved.

They are for my winter wheels, which are the 16" factory ones like this:

I'm trying to find them online, but it's confusing. I can determine I need ball seat ones, and there are 5 for every wheel, but I'm not sure of the length I need.

Any help is appreciated please!
