ProMaxx Spline Drive Lug Nut Closed End

ProMaxx Spline Drive Lug Nuts with a closed-end design are tuner-style wheel fasteners. They suit aftermarket wheels with small-diameter lug holes, where a standard hex or socket-style lug nut may not fit. Instead of a standard socket, a matching spline key installs and removes them.

Key Features:

• Closed-end design: The nut covers the end of the wheel stud. This helps keep out moisture and road debris, and it helps prevent rust from weeping onto the wheel finish.
• Spline drive: The exterior splines grip the nut for installation and removal. Because the nut has no tool recess inside, more of its length can engage the stud.
• Slim profile: The narrow body fits the tight lug wells found on many aftermarket and tuner wheels.
• Added theft deterrence: Removal needs a matching spline key, so the nuts are harder to take off than standard hex lug nuts.
• Quality construction: ProMaxx lug nuts are built to a Grade 10.9 hardness and have higher-than-OEM thread tensile strength. They come in a range of finishes and thread sizes.

Check that the thread size and seat style match your wheel studs and wheels before you install. Tighten to the torque specification recommended by your wheel or vehicle manufacturer. These closed-end spline drive lug nuts give aftermarket wheels a clean look and a secure fit.
