Frequently Asked Questions
Will these work on my stock wheels or only custom wheels?
They fit M12 x 1.25 studs, so fitment depends on your vehicle's lug pattern and stud size — check your owner's manual or current lug specs. The extended acorn design looks best on deeper-dish aftermarket wheels where the cap sits visible.
Do I need threadlocker or any special prep before installation?
Hand-thread them by feel first to confirm they seat properly on your studs. Most shops torque to factory spec from the service manual — don't over-tighten aluminum. Use a torque wrench for consistency across all five or four lug points.
Are these a full wheel replacement set or do I need to buy more?
Twenty nuts cover five wheels at four lug nuts each, or four wheels at five lug nuts each. Confirm your vehicle's lug count before checkout.
