Wheel Nut & Lug Nut Styles

When it comes to proper fitment, the lug style is just as important as the thread size and seat. Different types of wheels require different styles of wheel nuts. For example, most aftermarket wheels will require a small diameter lug while most factory style wheels will require a larger diameter lug. Most small diameter lugs will be unsafe to install on factory wheels.

Acorn Style

Acorn lug nuts are named as such because they resemble the look of an acorn. The term acorn refers to the ball-type, rounded, or dome head design of the lug nut.

Bulge Acorn Style

Bulge acorn lug nuts feature the same ball-type, rounded, or dome head design of the acorn lug nuts. However, bulge acorn lug nuts typically provide over 6% more seating surface area than a standard acorn lug nut.

Bulge Acorn XL Style and Bulge Acorn XXL Style

Bulge acorn XL lug nuts have the same features as a bulge acorn lug nut with a rounded dome head and increased seating area. However, the XL refers to a longer lug nut designed fit vehicles with longer wheel studs.

OEM Style

OEM style lug nuts feature a unique design built by different vehicle manufacturers such as Ford, Honda, Jaguar, Land Rover, Toyota, and more. These lug nuts are made to fit specific vehicle makes and models.

Spline/Tuner Style

Spline, or tuner, lug nuts are specifically designed for installation on most aftermarket wheels and are not intended for use on factory wheels. These lug nuts feature a small diameter and require the use of a spline tool for installation and removal.

Spline/Tuner Duplex Style

Spline, or tuner, duplex lug nuts have the same features as regular spline/tuner lug nuts and are specifically designed for installation on most aftermarket wheels only. However, the duplex refers to the larger thread size and thread pitch. Spline/tuner duplex lug nuts are designed for light trucks and are usually open-end.

Spline/Tuner Duplex XL Style

Spline, or tuner, duplex XL lug nuts have the same features as regular spline/tuner lug nuts and are specifically designed for installation on most aftermarket wheels only. However, the duplex XL refers to a longer lug nut designed to fit vehicles with longer wheel studs. Spline/tuner duplex style lug nuts are designed for light trucks.

Spline/Tuner ET Style

Spline, or tuner, ET lug nuts have the same features as regular spline/tuner lug nuts and are specifically designed for installation on most aftermarket wheels only. However, the ET refers to the extended thread. These lug nuts are intended for lug centric applications.
