Frequently Asked Questions
Do these fit my vehicle's stock wheel studs?
These are M12x1.5 metric threads — confirm your existing lug nut or wheel stud matches this spec before ordering. If you're unsure, check your vehicle's service manual or measure the thread pitch on a current lug nut.
Do I need special tools to install these?
The included adapter socket works with standard socket wrenches and impact tools. Use the same installation method as your current lug nuts — no custom equipment required.
Can I reuse the adapter socket if I buy a second set?
Each set ships with one adapter socket. If you're buying multiple sets and want to minimize your socket count, you only need one per install job — the socket isn't consumed during use.
