What is the torque range of a torque wrench?

[VanSadie]

The minimum torque range of a torque wrench is 5N.m, and the maximum is 25N.m. Precautions for hydraulic torque wrenches: The torque of a hydraulic torque wrench does not start from 0; it is also determined by the hydraulic wrench pump. Because the hydraulic wrench pump is a two-stage or three-stage pump, during low-pressure and high-flow conditions, whether it's a gear pump or a plunger pump, there is significant overflow, resulting in unstable pressure and unstable torque output from the wrench. Precise torque measurement starts from the second stage, where the flow rate is much smaller than the low-pressure flow, with no overflow, ensuring stability and allowing for precise torque control. Precautions for using torque wrenches: Do not use a preset torque wrench to remove bolts or nuts. It is strictly prohibited to add an extension sleeve to the end of the torque wrench to increase the leverage, as this may damage the wrench. Adjust the required torque as needed and ensure the adjustment mechanism is in the locked position before use.
