Fitment and specs

  • Thread size: 7/16"
  • Spline drive spike style lug nut
  • Bulge acorn (conical) seat
  • 4.4" overall length
  • Spline key included

Begin each nut by hand so the threads catch square, then tighten in a crossing sequence and torque to your vehicle's factory specification. See the torque reference chart for the pattern, and re-torque after the first 50 to 100 miles.

Common questions

Do these match my wheel's lug seats?
They are a bulge acorn (conical) seat. Conical, ball, and mag seats are not interchangeable, so verify your wheels take a conical seat before installing.

How do I confirm the thread size?
These are 7/16". Match that to a lug nut already on your vehicle or the applications listed in the description above.
