Fitment and specs
- Thread size: 12mm diameter, 1.5 thread pitch
- Style: open end bulge acorn
- Finish: nickel plated
- Sold individually, priced per piece
Thread each nut on by hand first so you feel any resistance before a tool ever touches it, then tighten in a star pattern to your vehicle's spec. Our torque reference chart is a good starting point, and plan on a re-torque after 50 to 100 miles.
Common questions
How many should I order?
These are priced per piece, so order one for every wheel stud on your vehicle. Count the studs on one hub and multiply by the number of wheels you are servicing.
My old lug nuts have a flat washer or a rounded seat. Are these a match?
No. Conical acorn, mag (washer style), and ball seat lug nuts are not interchangeable, because each seats against the wheel differently. This bulge acorn nut belongs on wheels machined for an acorn style seat, with the 12x1.5 thread matching your studs.
