Most men, doing household chores, do not pay much attention to the accuracy of threaded connections. As a rule, they are all tightened with ordinary keys until they stop, but, in principle, this is quite normal at home. High torque accuracy is needed mainly in the assembly of equipment. Therefore, when performing assembly work, a specialist should have at least a torque wrench on hand,not to mention a whole set of such tools.
Assignment of torque wrenches
In the process of designing machinery, equipment and everything that has a threaded connection, engineers provide a 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 undercompressed, while others will be pinched. 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 be possible to make special markings for this. Only a torque tool can solve this issue.
Advice for beginner technicians
Soas 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 twist with such a key, you need to know how the torque value is measured.
For those who buy a torque wrench, the instruction will tell you what simple tricks you can do with it. But in fact, everything is very simple and understandable even for novice technicians. But first you need to choose the key type. They are of two types: marginal and indicator. Indicator keys differ from the type of indicator showing the torque value: pointer, scale and, of course, digital.
The limit type torque wrench is designed for quick 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 tighten the key to the set limit. Such a tool is used when it is necessary to tighten a large number of threaded connections with the same torque value. The scale key shows the torque value only during tightening. The main caution when working with a dial and arrow key 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. Most convenientuse a key with an indicator tool, but if this is not at hand, then the dial and arrow keys are just as accurate, you just need to know how to use them. The arrow key has two arrows indicating the minimum torque value and the maximum value, respectively. Focusing on them, you can achieve maximum tightening accuracy.
