Common questions
What is the difference between open end and closed end lug nuts?
An open end nut has a through hole, so the stud can extend past the top of the nut. A closed end caps the stud for a cleaner look but limits how long the stud can be. Open end is the safer choice when your studs run long.
Are all lug nut seats the same?
No. Acorn nuts use a tapered seat that must match a tapered lug hole in the wheel. Mag and ball seat wheels need their own nut styles, so match the seat before you order.
