Breakaway torque is the rotating force required to break the head loose, going in the same direction as applied-tightening. This will usually give a value HIGHER than the original tightening torque because dynamic (when the bolt was tightened) is lower than static (when you try to break loose the bolt head). This is how it is defined by torque testing standards. If the breakaway is measured in reverse (loosening), you will usually get even higher readings because the bolt head generally digs in and forms small burrs and indents THAT ARE DIRECTIONAL-like a ratchet. It is incorrect to check breakaway by loosening.
10 most extreme places on Earth. In physics and mechanics, torque is rotational force, or the force necessary to cause an object to rotate around an axis. In most cases, more torque is needed to start the rotational motion than is needed to keep it going once it has begun. This initial force is called breakaway torque. The amount of breakaway torque needed to move something is determined in part by static friction. Static friction is the force that exists between two physical bodies to keep them from moving. For example, a wing-nut may have high breakaway torque because there is a lot of static friction between the nut and the bolt.
