Common questions
Do these need to match my wheel's seat style?
Yes. Conical, mag, and ball seat lug nuts are not interchangeable, and a mismatched seat will not clamp the wheel safely. Compare the duplex acorn profile in the drawing to the hardware your wheel calls for before ordering.
How do I confirm 9/16"-18 is my thread size?
Remove one lug nut and check the stud: 9/16" diameter with 18 threads per inch, or check your vehicle or trailer spec sheet. If your studs are stamped "L" or loosen clockwise, you need a left-hand thread version instead of this right-hand nut.
