ICON Alloys Splined Lug Nut Kit M14 x 1.5 Black 32-Count with Key

The ICON Alloys Splined Lug Nut Kit provides 32 closed-end splined lug nuts in a black E-Coat finish, sized for M14 x 1.5 threaded wheel studs with a 60-degree conical seat, plus a matching splined installation key. The narrow-profile splined design is intended for aftermarket wheels with tight lug pockets where standard hex sockets cannot seat cleanly.

Clearance Where Standard Sockets Cannot Reach

The splined outer profile replaces the hex flats found on conventional lug nuts, reducing the overall diameter of the drive surface. In wheels with deep, narrow lug pockets (common on many modern aftermarket designs), this narrower profile allows the socket to seat fully without contacting the wheel face, which reduces the risk of finish damage during installation and removal.

Closed-End Construction and E-Coat Finish

The closed end caps each lug nut, blocking moisture and road debris from reaching the exposed stud threads. The black E-Coat finish bonds to the metal surface rather than sitting on top of it, giving the nut a consistent matte-black appearance that resists corrosion and pairs with a wide range of wheel finishes without adding visual clutter.

Specifications

Who This Is For and Isn't

This kit suits builders fitting aftermarket wheels with M14 x 1.5 conical-seat lug pockets, particularly wheels with narrow or deep pockets where standard hex lug sockets cannot seat without touching the wheel face.

These lug nuts are not compatible with ball-seat or mag-seat wheel applications, and they do not fit M12 or any thread pitch other than M14 x 1.5. No torque specification is included in the kit.

Common Questions

What thread pitch do these lug nuts use?

The ICON Alloys splined lug nuts are manufactured for M14 x 1.5 threaded wheel studs. This is the thread pitch found on many full-size trucks and SUVs; verify your vehicle's stud thread pitch before ordering.

What seat type is required on the wheel?

These lug nuts use a 60-degree conical (acorn) seat. The wheel must have matching 60-degree conical lug seats for proper centering and clamping. They are not suitable for ball-seat or flat/mag-seat wheels.

What tool is needed to install and remove these lug nuts?

The kit includes one splined lug nut key designed specifically for this splined profile. Standard hex sockets will not engage the splined drive surface. Keep the included key accessible for future tire rotations and wheel removal.

How many lug nuts does the kit contain?

Each kit contains 32 splined lug nuts and one matching installation key. Thirty-two nuts is enough for a full set of five wheels (including a spare) on a vehicle with six-lug hubs, or for four wheels on an eight-lug application with four nuts remaining.

Is there a California Proposition 65 warning for this product?

Yes. California residents: this product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm.
