The rounded ball seat has to land in a matching rounded pocket in the wheel, so confirm your wheels are machined for ball seat hardware before installing. Hand start each bolt, tighten in a star pattern, and set final torque with our torque reference chart. Re-torque after 50 to 100 miles.
Common questions
How do I tell ball seat from conical seat?
Look at the contact surface behind the bolt head. A rounded dome is a ball seat, while a straight angled taper is conical. The wheel's bolt holes mirror the same shape, and the two are not interchangeable.
Will these work on aftermarket wheels?
Usually not without checking first, since many aftermarket wheels are drilled for conical seats. These bolts suit wheels machined for ball seat hardware, which is common on the factory wheels of the makes listed above.
