Frequently Asked Questions
Will these work with my factory wheel studs?
These are M12x1.5 thread — confirm your vehicle uses that specification before purchase. If your studs are a different pitch or diameter, these won't fit. Check your owner's manual or existing lug nut markings.
Do I need any tools to install these?
You'll need a socket that matches the 40mm head and a torque wrench. The adapter is included to help with installation, but final tightening must follow your vehicle's spec — check your service manual for the correct torque value.
Can I use these with my TPMS sensors?
The open-end design is specifically made to work around tire pressure sensors without removal or obstruction. This is one of the main reasons shops choose open-end nuts on sensor-equipped wheels.
