Background

For environmental reasons, the hexavalent chromium was removed from the surface treatment of wheel bolts. As a result, not all corrosion requirements can be fulfilled. The surface treatments that do fulfil corrosion requirements cannot be used as, amongst other things, they do not fulfil the technical requirements for maintaining wheel bolt torque.

In the case of customer complaint, the following procedures must be carried out.
