What is the specific method of using a torque wrench?

The wrench is a tool for rotating the bolts or nuts of the car. Pulling force should be used when turning the wrench. Pushing the wrench is extremely dangerous. The torque wrench can be used to tighten the bolt. Before the bolt is tightened, the bolt should be cleaned and lubricated. When the wrench tightens the bolts, the force should be applied evenly, and the impact force should not be used.

What is the specific method of using a torque wrench?

(1) The opening size of the selected wrench must match the size of the bolt or nut. If the opening of the wrench is too large, it will easily slip off and damage the hexagon of the screw. In the maintenance of imported cars, attention should be paid to the selection of wrenches in metric and imperial systems; all kinds of wrenches According to the selection principle, the socket wrench is generally preferred, followed by the ring wrench, the open-end wrench again, and the adjustable wrench at last;

(2) In order to prevent the wrench from being damaged and slipped off, the pulling force should be applied to the thicker side of the opening. This point should be paid special attention to the adjustable wrench with a larger force, so as to prevent the opening from appearing in a "eight" shape and damage the nut and wrench;

(3) The torque wrench is designed according to the strength of the human hand. When encountering tighter threaded parts, the wrench cannot be hit with a hammer; except for the socket wrench, other wrenches cannot be set with a booster rod to prevent damage to the wrench or threaded connectors;

(4) When using the torque wrench, it is most suitable when you hear a "snap".

What are the precautions for using torque wrench?

1. torque wrench is a precision mechanical instrument. Care should be taken when controlling, and the force should not be applied suddenly to cause the internal mechanism to fail.

2. Do not use the torque wrench as a hammer, handle it with care and do not throw it away.

3. It cannot be disassembled at will. After replacing parts, it should be sent to the calibration team for calibration to confirm whether its functions meet the requirements.

4. Do not work beyond the range. When the set value is reached and the clicking sound is heard, the afterburner should be stopped.

5. Do not use foreign matter to block, glue, fix the torque adjustment sleeve or handle.

What is the reading method of the torque wrench?

(1). If it is a torque instrument with a watch. The data indicated by the direct read pointer is the measured data value.

(2). If it is a sleeve plus a secondary scale indicator. The scale value on the main scale should be read first, and the sum of the scale value on the sub-scale or microtube is the measured data value.
