Does anybody have any pictures of stock wheel bolts? Are they full threaded? I need to see if I need new/shorter bolts for the steel spare. I will probably by generic ball seat bolts and shorten them. The official MB spare wheel bolts are like $5-6 each.

 

There is a dimension that you add to the stud where it sticks out of the wheel and that is the bolt length. I think the dimension added is .44. Just measure the amount the bolt sticks out the stock rim and add that to the amount of stud inthe wheel and you have it.
The stock Crossfire bolt is not threaded for about .66".
From the ball to bolt junction to the end of the thread is 1.54".
You should repeat this question in your spare tire thread and keep the info in one place.

 

Thanks, that is what I figured from pics of Mercedes ones.
I did it in a separate post because really 2 different items, but related for my purpose. The aftermarket bolts are typically fully threaded, so I may just buy 5 -10 of those, and cut them down, if I can't find any locally.

 

There are sites online that have bolts of almost any length and thread, both conical and ball and are not expensive at all.
