Frequently Asked Questions
Will these fit my current wheels?
These are M12x1.25 threads at 40MM height — check your vehicle's factory spec or current lug nut threading before ordering. Thread pitch and diameter must match exactly.
Do I need special tools to install these?
The open-end design works with a standard 22MM socket or wrench. No adapter needed. Torque to your vehicle's specification using a torque wrench — do not rely on feel alone.
Will aluminum lug nuts damage my wheel studs?
Aluminum is softer than steel, so over-tightening can strip threads on both the nut and stud. Tighten firmly, then verify torque with a calibrated wrench — do not exceed factory specifications.
