Frequently Asked Questions
Will these fit my factory wheels or do I need deep-dish rims?
M12 x 1.5 is the standard thread size across most vehicles, so fitment is about bolt hole diameter, not wheel style. The 50mm extended length is specifically designed for deeper offsets and larger brakes — if your current lug nuts are standard length and working fine, you only need these if you're upgrading to deeper wheels or wider brake hardware.
Do I need a special tool to install these?
Installation uses standard lug nut sockets and a torque wrench. The spline-drive design is a locking feature, not an installation requirement — you tighten them like any other lug nut. Check your vehicle's service manual for the correct torque spec.
How do the locks work and will they loosen over time?
The spline-drive mechanism creates a mechanical lock between the nut and wheel — no separate key tool needed. Tightened to spec, the design resists vibration loosening. Periodically re-check torque after 100 miles and then as part of regular maintenance to stay safe.
