Web23 apr. 2024 · Essentially, spontaneous loosening or rotational self-loosening occurs when a bolt rotates loose because of shock, vibration, or dynamic loads. Even a slight rotation can be enough for a bolted joint to lose all of its preload. This is the most typical cause of bolt loosening. “Settlement is critical when it happens due to dynamic loads. Webfactor. The stem factor mathematically represents the mechanical process by which the rotational motion of the stem nut is converted to linear motion of the stem. Figure 3-22 illustrates this mechanical process and shows details of the stem thread. If both the stem thrust and the actuator torque are measured in a test, the stem factor
