Frequently Asked Questions
Will these work with my current wheel studs?
These are M12×1.25 thread — confirm your wheel studs match before ordering. The adapter helps bridge minor fitment gaps, but the stud size must be correct.
Do I need a special socket to install these?
The open-end design works with a standard 40MM socket or wrench. No custom tooling required — hand tools you already own will do the job.
Can I reuse my old lug nuts if these don't fit?
Yes. Test-fit one nut on a wheel stud before committing to the full set. If the thread pitch or hole size don't match, swap back to your originals with no issues.
