The thread of most screws has a certain direction and can be turned clockwise to lock the screw. This screw is called a right hand screw.Left-turn screws, as opposed to the above screws, are used only in certain situations. For example, in some applications, the screws are subjected to counterclockwise torque, and the torque applied to the right-turn screws may cause the screws to loosen. In this case, the left-turn screws are used, such as the left-hand pedal of a bicycle.However, the wheels on the left and right sides of the car are tightened by the right screw, and there is no data to show that the wheel loosening is directly related to the screw grain
