　　How to read the torque value of a torque wrench?

1. How to read a torque wrench. There is a window on the handle of the torque wrench. There is a ruler in the window. The ruler displays the torque value. There is a standard line on the edge of the window. When the line on the scale is aligned with the standard line, the torque value at that point represents the current torque preload value.

2. Choose a torque wrench with an appropriate range. When using a force wrench, you must first select a torque wrench with a moderate range according to the requirements of the workpiece to be measured. The measured torque value should not be less than 20% of the range of the torque wrench in use. A range that is too large is not suitable for use on parts with small torque. Reinforced, small-range torque converters cannot be used beyond the range.

3. The method to check the scale of the torque wrench is: read directly from the scale where the pointer on the edge of the handle is aligned. The scale value to which the handle is screwed is the set torque value. The torque value is Newton meters or kilograms of meters. The scale is written unit.

4. You can control the twisting direction of the torque wrench; the scale on the wrench rod and the circle of numbers on the handle represent the torque range of the wrench, in Newton meters (Nm).

5. First, clearly see the torque unit of the torque wrench. Some are Nm and some are kilograms. Second, clearly see the difference between the two red ones. The red difference divided by 10 is the torque represented by each small grid. Third, the red The torque plus the torque of the small black grid is all the torque.

6. There are numerical values on the surface of the preset torque wrench. When setting, you only need to rotate the knob to the desired value. When assembling car parts, there are many places where a torque wrench is needed, such as tightening the valve cover screws, screwing the shock absorber screws, screwing the screws that fix the wheels, etc., all of which require the use of torque wrenches.
