Torque wrench is a measuring tool used to measure the torque value of an object. It is often used to test the reinforcement torque and the destructive torque.

The most commonly used manual torque wrenches include dial-type torque wrenches, pointer-type torque wrenches; in addition to electric torque wrenches, pneumatic torque wrenches, etc. The torque wrench has a wide range of applications. When strengthening the torque, you only need to set the required value to operate. Relatively speaking, it is relatively simple.

1. In the use of a torque wrench, first select a moderate range according to the requirements of the measurement part. The measured torque value should not be less than 20% of the range of the torque device in use. A too large range is not suitable for small torque parts. Reinforced, small range torque device can not be used over range, otherwise the instrument will be easily damaged.

2. When using a torque wrench, first connect the force-bearing pawl to the auxiliary accessories (such as sleeves, various batch nozzles) to ensure that the connection is no problem. Before strengthening the torque, set the force value that needs to be reinforced, and Lock the locking device, and then adjust the direction switch button to apply a uniform force in the direction of the force. When the applied torque reaches the set value, the wrench will make a "click" sound or the wrench joint will bend a little angle. The representative has been tightened and no more force is required.

3. When measuring, the hand should grasp the effective range of the handle, and slowly apply force in the direction perpendicular to the tube body until you hear the sound after reaching the set value. In the process of applying force, follow the national standard instrument Operating norms, the vertical deviation should not exceed 10 degrees left and right. The vertical deviation should not exceed 3 degrees in the horizontal direction.
