Frequently Asked Questions
Will these fit my vehicle's lug pattern?
These are M12 x 1.25 metric threads. Verify your vehicle uses this thread size before purchasing — check your owner's manual or existing lug nuts. Wrong thread pitch will not seat properly.
Do I need a special socket to install these?
Yes. Spline-drive lugs require a corresponding spline socket — standard cone or ball seat sockets won't grip properly. Use the correct spline socket size for your M12 application.
Can I mix these with my existing steel lug nuts?
Not recommended. Use all 20 aluminum lugs together on a single wheel set for consistent clamp load and durability. Mixing metals and weights across wheels creates uneven pressure distribution.
