Instructions for use and use of a torque wrench
In order to transfer the necessary force to the threaded connection, you must correctly use any torque wrench. When using the tool, it is necessary to follow the basic recommendations and rules for using a torque wrench:
After reviewing the basic instructions for using the Best Torque Wrench, we suggest figuring out how to properly tighten the bolts with a torque wrench of different types of this tool. In the previous article, we examined the maintypes of torque wrenches, their features, advantages and disadvantages.
- Using the key as an ordinary screwdriver or ratchet will increase tool wear, so the key should only be used for its intended purpose;
- Use only standard or high shockless end nozzles;
- To ensure the accuracy of the transmitted force, it is recommended to use only one transition of the assembled tool, i.e. one end head between the tightened fasteners and the connecting square of the key;
- It is forbidden to increase the lever arm using a variety of extensions, for example, pipes;
- It is not recommended to throw or knock on the instrument;
- If the key was only bought or has not been used for a long time, then in order for the internal mechanisms of the tool to be lubricated, several loads must be done at the minimum value of the torque range;
- After work, the key is best stored in a clean and dry place. And for long-term storage, it is better to carry out the preservation procedure, lubricating the key body with a thin layer of oil;
- After measurements, the tool must be set to the initial zero value so that the mechanism spring does not stretch, while maintaining the accuracy of the tool measurements;
- Subsequently, the spring in the keys still weakens. Therefore, annually or more often it is necessary to check and adjust (calibrate / verify) the instrument on a special stand in order to increase the accuracy of the instrument.

How to use a snap type torque wrench?
This type of key is the most common and popular tool among professionals and amateurs. During operation, it is not necessary to control the force values. The principle of operation of the torque wrench is as follows: upon reaching a pre-set value of force, the key emits a click, which indicates completion of work, and the tool, slipping, will not transmit more force to the fastener than was installed on the scales of the tool.
In order to use the torque wrench correctly snap type you need to know how to set the desired value using the main and auxiliary scales.

Torque wrench instruction manual snap type:
- Unscrew the lock nut at the bottom of the key handle;
- Set the load value on the main vertical scale using the rotary handle. And if necessary, then you need to set the torque value on an additional dial on the bottom of the handle to get the desired force value. It turns out that the value is added up from both scales, fixing the final effort;
- We twist the lock nut at the bottom of the key handle to fix the set force
