Most men, performing household chores, do not particularly pay attention to the accuracy of threaded joints. As a rule, they are all tightened with ordinary keys all the way, but, in principle, at home this is quite normal. High precision torque is needed mainly when assembling equipment. Therefore, when performing assembly work, a specialist should have at least a torque wrench under his hand, not to mention the whole set of such a tool.
Torque wrench designation
In the process of designing machinery, equipment and everything that has a
threaded connection, engineers provide for the torque value for each connection. Violation of these values will entail a violation of the assembly technology, and as a result, some
threaded connections will be uncompressed, while others are clamped. The consequences of a loose nut due to loose tightening can be serious, depending on the equipment. But it is impossible to determine the value of the torque by eye, and it will not work to do special markings for this. Only a torque tool can solve this problem.
Beginner Tips
Since a torque wrench is rarely used to solve household technical issues, not everyone knows how to use it. It is not enough to be able to spin with such a key; you need to know how the value of torque is measured.
For those who buy a torque wrench, the instruction will tell you what simple tricks you can make with it. But in fact, everything is very simple and understandable even for novice technicians. But first you need to select the type of key. They are of two types: limit and indicator. Indicator keys differ from the type of indicator that displays the value of torque: dial, dial and, of course, digital.
The torque wrench of the ultimate type is designed to quickly tighten any threaded connections. The principle of its operation is based on the fact that it accurately sets the required torque value, and it will not be possible to exceed this value, and therefore all that is needed is to turn the key to the set limit. Such a tool is used if it is necessary to tighten a large number of threaded connections with the same torque value. The dial gauge displays the torque value only during tightening. The main warning when working with the dial and arrow keys is not to exceed the maximum torque so as not to damage the key mechanism.
The indicator type torque wrench is designed for the most accurate tightening of threaded connections. It is most convenient to use a key with an indicator tool, but if this is not at hand, the scale and arrow keys are just as accurate, you just need to know how to use them. The arrow key has two arrows showing the minimum torque value and the maximum, respectively. Guided by them, you can achieve maximum accuracy.
