Screw fastening and evenness are especially important when installing carbon fiber parts and lightweight parts, both of which are measured by torque during installation. In the correct torque range, it can not only clamp parts, but also prevent sliding teeth or damage. Therefore, torque wrench has become an essential tool for car shops and professional car drivers, what do we still need to pay attention to in use?

Strictly speaking, torque wrench is a measuring instrument. In particular, the mechanical preset torque wrench commonly used in the industry can only be used to determine the torque when tightening screws, and must not be used as a disassembly tool to loosen the already tightened screws. The preset torque wrench is usually used in one direction. When the screw is tightened clockwise and the preset torque is reached, the connecting rod is pushed to produce instantaneous disconnection effect and prompt sound. Although it is possible to switch counterclockwise operation through the pick of the ratchet wheel, it can only be used to screw out the loose screw

Its principle is that the screw fastening condition of static friction force is greater than the dynamic friction of loose condition, especially the screw to install after a period of time, when needed to loosen the screw torque than tighten torque (1.5 times), reverse use wrench internal leverage jammed easily, cause is not prompt, when using the irreversible damage.
