Have you ever notice how much of a pain it is to mount your wheels and insert the wheel bolts at the same time?
Well, this handy little pin from Mercedes-Benz solves that problem.
Insert this pin into the uppermost bolt hole and literally hang the wheel on it while inserting four of the wheel bolts.
You then remove the pin and insert the final wheel bolt.
Pretty simple, eh?
Thread pitch is M14 x 1.5.
Original Mercedes-Benz part.
