Torque wrench - also known as a torque wrench or torque wrench or torque wrench, torque is the product of force and distance. When fastening screws, bolts, and nuts and other threaded fasteners, you need to control the amount of torque you apply to keep the threads tight and not to cause too much torque to break the threads, so use a torque wrench. First, set an upper limit of the required torque value. When the applied torque reaches the set value, the wrench will make a "cata" sound or bend a little Angle at the joint of the wrench, which means that the wrench has been tightened without additional force.
