Start all the nuts by hand, snug them in a star pattern, then finish with a torque wrench set to your vehicle's spec from our torque reference chart. Skip the impact gun for final tightening, since it is easy to overshoot. Re-torque after 50 to 100 miles.
Common questions
Will these seat in my wheels?
They will if your wheel's lug holes are machined for a conical seat. Acorn, mag, and ball seat hardware are not interchangeable, so match the nut to the seat your wheel uses.
What size socket fits them?
A 3/4" hex. Use a socket in good shape that fits snugly, because a sloppy fit can chew the corners and mark the blue finish while you work.
