Will these fit my wheel studs?

M12x1.5 is a common metric thread pitch for many vehicles. Verify your stud size before ordering — if your car runs M14 or M12x2.0, these won't work. Check your owner's manual or existing lug nut to confirm the exact thread pitch.

Do I need to tighten these to a specific torque spec?

Yes. Refer to your vehicle's service manual for the correct torque setting — tightening too loose risks wheel movement, and over-tightening can strip studs or crack rotors. Different vehicles have different specs, so use a torque wrench and follow manufacturer guidance.

How do I clean and maintain the purple finish?

Wash with soap and water, dry with a soft cloth. The polyurethane coating resists corrosion, but harsh chemicals or abrasive scrubbing can dull the finish. Regular wheel cleaning during normal maintenance keeps them looking fresh.
