Hand-start every nut for the first few turns, work around the wheel in a star pattern, and finish with a torque wrench at your vehicle's spec. Our torque reference chart lists common values, and re-torquing after 50 to 100 miles is cheap insurance on any fresh install.
Common questions
How do I know my studs are 1/2"-20?
Older GM and Chrysler cars and trucks commonly use this size, but the sure test is threading one on by hand. The right size spins on smoothly to full depth. If it resists after a turn or two, stop and verify before going further.
Do these fit any wheel with 1/2" studs?
Thread size is only half the match. These are cone-seat acorn nuts, so your wheel's lug holes need a matching tapered seat. Wheels made for mag seat (flat with washer) or ball seat hardware require those styles instead.
