Confirm your wheels have the rounded ball seat pockets these bolts need, then hand start each one to protect the hub threads. Use a snug 17mm six-point socket and a torque wrench set to your vehicle's spec; our torque reference chart lists common values. Re-torque after 50 to 100 miles.
Common questions
Can I run these in wheels drilled for conical seats?
No. Ball and conical seats are not interchangeable. The rounded face of these bolts needs a matching rounded pocket in the wheel, which is typical of factory wheels on the makes listed above.
Why does the 39mm shank length matter?
Shank length sets how far the bolt reaches through the wheel and into the hub. Match it to the bolts you are replacing unless wheel thickness has changed, so you keep full thread engagement without bottoming out.
