For example, we take the tightening of the wheel bolt on the car, each car manufacturer prescribes different specifications of the tightening torque, so you have to adjust your torque wrench to the required specification.

What is the torque wrench?
We can say it is a type of tool used to precisely adjust the torque code tightening bolts or nuts. It is usually the key to a certain reception on Thursday with a special internal mechanism. The torque wrench is used when the tightening force of the bolts and nuts is crucial. To the user allows accurate measurement of the tightening torque used on the bolt or nut, and also allows it to be compared with the specification of the required tightening torque.
This allows proper strain and loading of all parts. The torque wrench is measured indirectly stress and load of bolts and nuts. Unfortunately, there is a certain in this measurement process inaccuracy that occurs due to different frictions between the bolts and the holes into which they are clamped. Measurement of the bolt stress is much more accurate, but in most cases, torque measurement is the only possible measurement that we can apply.
What are the good features of this tool and why should we have it?
Measuring tapes, overload protection torque wrenches, movable meters (including digital), spirit levels, angles, masonry battens, and measuring instruments are excellent representatives of precise measuring instruments, without which successful planning and execution of work are simply impossible to imagine.
Measuring tools are precise and at the same time easy to use, both for general measurements with classic measuring tapes and for various measurements when performing specific masonry and locksmith work, when measuring threads, calibration, and the like.
These precision measuring tools are available in the classic version as well as in digital versions with added timer and other functions. All tools are designed and manufactured under applicable international standards.
Where to buy torque wrenches?

How to choose the right torque wrench?
There are several types of torque wrenches that we need to differentiate according to the look and purpose of use, and they are torque wrench with an arrow, rotary, with a counter, and digital.
Torque wrench with an arrow
This wrench has two levers and works on the principle of a spring steel beam that bends under pressure. By applying a tightening force to the screw, the boom rotates. This key is not the most accurate and the reading error can be up to 10%.
Adjustable torque wrench
The first thing you need to do is adjust the torque value, and only then do you move on to tightening. Compared to the previous, adjustable torque, the key has a slightly higher precision – the error goes up to 4%.
Torque wrench with counter
This type can be said to have a very accurate counter and offers a precise reading of the tightening force, but it also has a drawback, and that is that you have to constantly monitor the dial during tightening. However, the big advantage is that the dial remains at the highest measured value, so we can easily continue the measurement.
Digital torque wrench
If we have to single out the one that has proven to be the most accurate and simple to handle, then it is certainly digital. The measurement is shown on the digital display, and it is up to you only to set the value of the tightening force. When the desired value is reached, a beep sounds to let you know.
Torque wrench opinions: is it practical to use?
From time to time it is necessary to calibrate the torque wrench that is performed on the calibration device. Calibration is one of the key factors in the proper maintenance of this tool as it affects accuracy.
All opinions on torque wrenches agree that it is an excellent tool to keep our vehicles in perfect condition, since manual wrenches can represent a danger for the parts that we tighten, for our goods (be they bicycles, motorcycles, cars, etc.) and for own safety.
It would be a real shame to break or deform a part, losing consistency or stability to our vehicle – which is not cheap at all – for not having bought a torque wrench to do this correctly. For this reason, it is highly recommended to buy torque wrenches to tighten the nuts and bolts, as we are thus taking care of our investment.
