Thread each bolt in by hand for the first few turns so any cross-threading shows up before it damages the hub. Snug all bolts in a star pattern, then tighten to your vehicle's spec using our torque reference chart, and re-torque after 50 to 100 miles of driving.
Common questions
My factory bolts have a rounded seat. Will these work?
No. These are conical seat bolts, and conical, ball, and mag seats are not interchangeable. The bolt seat must match the seat machined into your wheel, so check the wheel before ordering. Many aftermarket wheels take conical seat bolts even when the factory hardware was ball seat.
How many should I order?
These are priced per piece. Count the bolt holes on one wheel and multiply by the number of wheels you are fitting.
