Features of torque wrenches:
Torque wrench is a special tool that can be used in conjunction with the socket in the socket wrench to display the torsion moment. When a bolt or nut is tightened with a torque wrench, the magnitude of the torque can be indicated in time. The unit of torque is N•m. The specifications of torque wrenches commonly used in car maintenance are 0~300N*m. In maintenance operations, all bolts or nuts that require tightening torque require a torque wrench to tighten the bolts or nuts to the specified torque. The use of torque wrenches must comply with the regulations. Do not use them under overload conditions to cause inaccuracy or damage to the torque wrenches. After use, place the torque wrench steadily to avoid deformation of the wrench rod or wrench pointer caused by heavy objects, which may affect the accuracy of the wrench or even damage the wrench.
