Choosing the right wheel bolts

Seat shape is critical. There are two main families: conical (cone-shaped) and ball seat (half-sphere). Most aftermarket wheels, i.e. non-original, must be fitted with conical seat bolts or nuts.

Head length depends on the thickness of the wheel spacer fitted. For example, with an original head length of 37 mm and a 20 mm spacer, a head length of 57 mm is required. More information available from customer service.

Warning: for safety reasons, wheel bolts cannot be taken back or exchanged. Sold individually: please select the required quantity. For any questions before purchase, contact us.
