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.

These practices are not a means of obtaining or maintaining torque, rather a safety device to prevent the disengagement of screws, nuts, bolts, snap rings, oil caps, drain cocks, valves, and parts. Three basic methods are used in safetying; safety-wire, cotter pins, and self-locking nuts. Retainer washers and pal nuts are also sometimes used. [2]

A lug nut or wheel nut is a fastener, specifically a nut, used to secure a wheel on a vehicle. Typically, lug nuts are found on automobiles, trucks (lorries), and other large vehicles using rubber tires.
A screw thread, often shortened to thread, is a helical structure used to convert between rotational and linear movement or force. A screw thread is an inclined plane wrapped around a cylinder or cone in the form of a helix, with the former being called a straight thread and the latter called a tapered thread.
With lug bolts, on the other hand, the whole hub usually has to be replaced in case of stripped threads in the hub. One motivation for using lug bolts instead of wheel studs and nuts the number of parts that needs to be attached to the wheel hub. Wheel studs and lug nuts consist of two parts, while the lug bolt is a single part.
Today, torque is referred to using different vocabulary depending on geographical location and field of study. This article follows the definition used in US physics in its usage of the word torque. [5] In the UK and in US mechanical engineering, torque is referred to as moment of force, usually shortened to moment. [6]
Many connectors are keyed with some mechanical component (sometimes called a keyway), which prevents mating in an incorrect orientation. [20] This can be used to prevent mechanical damage to connectors, from being jammed in at the wrong angle or into the wrong connector, or to prevent incompatible or dangerous electrical connections, such as ...
