The wheel center nut is used to secure the wheel to the car. This nut is screwed onto the hub and fixed to prevent the wheel from unscrewing while driving. The seat has a taper, so the nut fits tightly onto the hub and jams the wheel disc on the hub. Due to the taper of the hub, the wheel is better installed in the center. At the end of the hub, there is a special thread onto which the wheel nut is screwed. The thread itself has a diameter of 75 mm and is carefully processed for better fastening. The wheel nut is tightened with a torque of 300 Nm to ensure proper fixation and prevent problems with unscrewing or skewing the wheel. The wheel nut is not hexagonal, but toothed, when fastened, these teeth are inserted into special grooves of the impact wrench. Many teeth on the nut for tightening are made so that the head of the impact wrench easily gets into the grooves of the nut. A racing car uses a single center nut to secure the wheel because it is easy to remove and secure the wheel during the race using only one nut. In racing conditions, pit stop time is critical, using a single center nut to secure the wheel significantly speeds up the process of changing the wheel during the race. It is convenient and efficient, as mechanics only need to focus on one point to quickly change the wheel. In addition, the conical shape of the nut allows for easy and accurate alignment of the wheel on the center, which is important for ensuring stability and preventing vibrations during the race. Efficiency and speed of maintenance play a key role in the world of motor racing, and the design of the center nut for securing the wheel is one of the aspects that helps optimize this process.
