Should a lug nut become loose, the pointer will move in line with the movement of the lug nut, i.e. the tips no longer point to each other. The wheel nut indicators allow not only a quick and efficient check of the wheels by the driver, but also by the control authorities. In addition, the inspection can be easily documented with a photo.
Installing a wheel with a lug wrench thus requires a bit of rough guessing about proper tightness. Excessive force can strip threads or make the nuts very difficult to remove. Also, uneven torque between the various lug nuts, or excessive torque, can lead to warping of the brake rotor if the car is equipped with disc brakes.

A lug nut or wheel nut is a fastener, specifically a nut, used to secure a wheel on a vehicle.

When utilizing locking wheel nuts, one standard lug nut on each wheel is replaced with a nut that requires a unique key (typically a computer-designed, rounded star shape) to fit and remove the ...
The retaining nut requires a large amount of torque to secure, therefore a long-handled torque wrench or a powerful impact wrench (also called a "wheel gun") is used to tighten it. Wheels of this type are used on many modern racing cars, including NASCAR , Formula One and racing sports cars .
While the 9.5-inch rear end exhibits its own durability, it is generally considered less favorable for high-torque applications. The 9.5-inch C-clip rear differential was featured in both the Suburban and pickups, available in 6- or 8-lug variations, employing 33-spline axles.

With lug bolts, on the other hand, the whole hub usually has to be replaced in case of stripped threads in the hub.

Wheel studs and lug nuts consist of two parts, while the lug bolt is a single part.
