Frequently Asked Questions
Will these work with my thick aftermarket wheels?
The 44mm extended length is designed for deeper wheel center bores and aftermarket fitments where stock lug nuts sit recessed or flush. Measure your stud protrusion after mounting your wheels — if threads show past the wheel face, these will cover them cleanly with the acorn cap.
Do aluminum lug nuts need any special maintenance?
The red anodized finish protects against corrosion, but check torque after your first drive and monthly thereafter — aluminum can relax slightly more than steel. Retorque to your vehicle's spec using a torque wrench. Hand-knurled tightening is fine for initial assembly, but always finish with a wrench to spec.
What thread pitch is this, and how do I know it fits my vehicle?
These are M12x1.25 metric thread. Verify your vehicle uses this pitch before ordering — most modern cars and trucks use either M12x1.25 or M12x1.5. Check your OEM lug nut or service manual. You'll need five lug nuts per wheel, so a 20-piece set covers four wheels with spares.
