Tips: Differences among 3 main types of torque wrenches

Torque wrenches can be divided into electric, pneumatic and manual from the perspective of power source. There are three types of manual torque wrenches commonly used in the industry: click type torque wrenches, digital torque wrenches, beam/ dial torque wrench.

Each type of torque wrench has its own characteristics, and the occasions are different. For example, the click type preset torque wrench is mainly used for tightening the bolts at preset value, and the digital torque wrench and dial type torque wrench are generally used for torque detection. Generally speaking, the use of torque wrenches mainly lies in the precise control of bolt force values.

Here is a simple comparison among three types of torque wrench. Through the basic knowledge above, it is roughly classified as follows:

1. The degree of difficulty of operation: digital display type> click type> beam/dial type
Because the digital torque wrench can be classified as an electronic product, the torque setting, the mode selection and the use of some combination keys still have certain requirements for the understanding ability of the workers. Of course, the digital display torque wrench is not necessary for general workstations, but mostly used for testing. The click type torque wrench only needs to adjust the torque, which is easier to learn, while the beam / dial type torque wrench uses the traditional scale reading, the torque does not need to be adjusted, as long as it is used within the torque range.

2. Torque usage accuracy: digital display type＞dial type＞click type

3. Degree of difficulty in reading: digital display type (direct display of values) <dial type (watch type reading) <click type (knob scale + steel handle imprint scale)

4. Price: digital display type> dial type> preset type

5. In terms of brand selection, if the requirement is absolute quality, high procurement accuracy or other requirements for use, and price and delivery are secondary, then choose a well-known brand. This is no problem.
