Is the screw tighter or looser clockwise

Tightening the screw clockwise is the principle of ergonomic mechanics. Most people are right-handed and can use their right hand to tighten screws and bolts. Therefore, only turning clockwise will make it easier and harder. And the screws are tight in the clockwise direction and loose in the counterclockwise direction. This is determined based on the principle and structure of the thread. And the right-hand thread processing process is more convenient. Threads are divided into internal threads and external threads. Internal threads refer to the threads on the nut, and external threads refer to the threads on the threaded rod. Generally, the threads of threaded rods are external threads, and the threads of nuts are internal threads. Note that when using screws to fix items, the screws must be aligned. It should be stable during operation and should not be shaken or skewed to prevent items from being unable to be fixed. Screws cannot be used in very humid places. Because corrosion is easy to occur, the remaining screws must be placed in a dry place. Pay attention to the position and angle of the screw connections. Appropriate fixing points should be selected for the location of screw connections to ensure the stability of the screw connections. At the same time, the connection angle should be adjusted as needed to make full use of the mechanical properties of the screw.
