Common questions
My factory bolts are ball seat. Can I use these?
Only if the wheels you are mounting have conical seats. Seat type is set by the wheel, not the vehicle. Conical, ball, and mag seats are not interchangeable, and a mismatched seat will not center the wheel or hold torque correctly.
What does Grade 10.9 mean?
It is a metric strength class for the bolt steel. These are Grade 10.9 with enhanced torque tension, so they are built to take proper wheel torque and hold their clamping force between checks.
