According to the required constant force value, select the corresponding constant torque wrench that has passed the calibration, and do not use the constant torque socket wrench set that has not been calibrated. Twist the wrench with a balanced and slow force, do not twist it sharply, hold the middle point of the handle of the torque wrench with your hand, and pull the handle perpendicular to the center line of the wrench until the required torque is reached. .
Be sure not to apply a torque greater than the rated value of the constant torque wrench. Do not use the constant torque wrench to remove bolts or nuts. The constant torque wrench can only be run clockwise.
When tightening the bolts with a constant torque wrench, the following requirements must be observed: when the adapter has various shapes, it can be used reasonably; in order to reduce the tightening torque error, the length of the adapter should be less than the length of the constant torque wrench; when connecting the adapter , its center line should be in a straight line with the center line of the wrench. If necessary, an adapter with an axis offset can also be used, but the angle should not exceed 15°.
It is not allowed to use the constant torque wrench as an ordinary wrench, such as to loosen nuts or bolts.
The right-torque fixed torque wrench cannot be left-handed, and the left-torque fixed-torque wrench is not necessarily right-handed.
Do not touch titanium and alloy bolts or product structures with chrome-plated torque wrenches and adapter wrenches.
The torque applied by the constant torque wrench is not allowed to exceed the rated torque value of the constant torque wrench. Torque wrench is also called torque wrench or torque wrench. Its use is to adjust the torque first and then tighten the bolt. In harsh industrial environments, most of the tightening of high-strength bolts basically requires initial tightening and final tightening, and each step basically requires strict torque requirements.
