M12 x 1.5 Extended Closed End Lug Nuts — Aluminum
Lightweight aluminum closed-end lug nuts with extended body design for wheel fitment and corrosion resistance. The closed-end design keeps debris out of the stud hole, while the extended profile accommodates deep-dish and spacer applications. Aluminum construction reduces unsprung weight compared to steel.
Key Features
- Closed-end design - Keeps water and road debris from entering the wheel stud hole, protecting fasteners and studs.
- Extended body profile - Engineered for wheels with deep-dish patterns or when running spacers; extra length prevents bottoming out.
- Aluminum material - Lighter than steel equivalents; reduces rotational mass and unsprung weight on each corner.
Specs

- Thread size: M12 x 1.5

Frequently Asked Questions
Will these work with my deep-dish wheels?
Yes — the extended body profile is designed specifically for wheels with aggressive dish and offset. If you're running spacers, the extra length prevents the nut from seating before the fastener fully engages. Test-fit one wheel to confirm engagement before installing all four.
How tight should I torque these?
Refer to your vehicle's service manual for the correct torque specification — it varies by stud size and vehicle. Use a calibrated torque wrench and tighten in a star pattern for even clamping pressure.
Do aluminum lug nuts require any special care?
Aluminum is softer than steel, so avoid cross-threading during installation — hand-start each nut first. The closed-end design sheds water naturally, but periodic cleaning with a dry cloth keeps them looking fresh and prevents corrosion.
