Fitment and specs
- Thread size: 9/16"-18
- Style: open end bulge acorn
- Finish: nickel plated
- Sold individually, so you can order exactly one per stud
Thread each nut on by hand first to confirm it spins freely, then tighten in a star pattern to your vehicle's spec using our torque reference chart as a guide. Re-torque after 50 to 100 miles of driving, since freshly installed hardware can settle slightly.
Common questions
Will these seat correctly on my wheels?
Bulge acorn lug nuts use a tapered cone seat, so your wheel's lug holes need a matching conical seat. Cone, mag, and ball seat styles are not interchangeable, and a mismatched seat will not clamp the wheel properly.
What does open end mean?
There is no closed cap on top, so the stud can pass all the way through the nut. That makes this style a practical choice when your studs are too long for a capped acorn nut to fully tighten.
