Rounded wheel bolts
 

Sorry for the stupid question and the rant. Finally got around to changing out the wife's Q5's summer tires to her snow tires. Besides the summer tires being over-torqued, the heads are rounded. I won't blame the last mechanic necessarily for the latter as I didn't inspect them before this, but I feel a need to replace them now. Looking for OEM (they look different than what I was used to on my VW's) but am horrified by the price. Best price I found was 10 bucks each! Really?! I know its and Audi, but its just a bolt, right? Any one know of a less expensive OEM or have a suggestion for aftermarket bolts? Is there anything that I need to watch out for as I search for aftermarket bolts? Guess I have to stop being lazy and go back to rotating my own tires. Ok, thanks for your patience, I feel slightly better now.

Thanks for the response. Certainly the price is nice. The photo does not look like the bolts that I have though and I was hoping to replace with OEM which have a 2 piece design. Also I have found out that there are different thickness wheels and a VIN is needed to make sure that I have the right bolts. More work to do before finding the right replacement. Thanks again.

Do you have a set of calipers? The bolt is a floating seat, so you need to know head size, if the seat is ball or conical, the thickness of the base of the taper or ball (known as the "R" number), and the length of the threaded section of the bolt.
