Torque wrenches are produced in the form of "click-type alarm wrenches", which are used by adjusting the wrench to the torque value you need, and when the wrench is used to lock the bolt, it will make a click sound when the torque value is reached. Loosen the bolt immediately to avoid overtwisting. "Bent torque wrench". When the lock bolt reaches the preset torque value, the front end of the wrench will bend, indicating that the torque value has been reached. "Self-sliding torque wrench", when reached the preset torque value, the front end will automatically slide, no more force, never over-torque. Simply put, torque wrenches are designed to lock bolts precisely. Generally, the torque value of the lock bolt is preset first, and then when the wrench alarm indicates that the torque value of the lock bolt has reached. Prevent the bolt from breaking when the torque is too high or the bolt is easy to become loose when the torque is too small.
