Frequently Asked Questions
Will these work with my factory wheel studs?
Yes—M12x1.25 is a common metric stud size. Verify your vehicle uses this thread pitch before ordering. If unsure, measure an existing lug nut or check your service manual.
Do I need to torque these differently than steel lug nuts?
Follow your vehicle manufacturer's recommended torque spec—it applies regardless of material. Aluminum seats the same way as steel; the knurled surface just makes hand-snugging easier during installation.
Can these be reused or are they single-use?
These are reusable. Remove them cleanly, store in a dry place, and reinstall on future wheel changes. Inspect the threads and acorn cap for damage before reuse.
