Torque wrench for high accuracy of tightening
Most men, doing household chores, do not pay much attention to the accuracy of threaded connections. As a rule, they are tightened with usual keys until they stop, but, in principle, at home it is quite normal. High accuracy of torque is necessary mainly in the assembly of equipment. Therefore, when performing assembly work, a specialist must have at least a torque wrench, not to mention a whole set of such a tool.

Tips for beginners
Since the dynamometric key is rarely used to solve domestic technical issues, not everyone knows how to use it. This key is not enough to be able to twist, you need to know how to measure the value of torque.
The torque wrench of the limiting type is intended for fast tightening of any threaded connections. The principle of its operation is based on the fact that the required torque value is precisely set on it, and it will not be possible to exceed this value, and therefore all that is needed is to screw the key to the set limit. This tool is used when it is necessary to tighten a large number of threaded joints with the same torque value. The dial key shows the torque value only during tightening. The main precaution when working with a dial and spanner key is not to exceed the maximum torque so as not to damage the key mechanism.
Dynamometric wrench type indicator is designed for the most accurate tightening of threaded connections. It is most convenient to use a key with a tool indicator, but if there is not one under the hand, then the scaling and arrowheads are just as accurate, you just need to know how to use them. The arrow key has two arrows showing the minimum value of torque and the maximum, respectively. Orienting on them, you can achieve the maximum accuracy of tightening.
