Very often, you make the mistake of tightening the bolts, but also the screws, too, more than necessary. It is believed that in this way, the grip is firmer, but it is not so. Tightening too much, or to use a more appropriate and technical term, tightening the bolts too much can damage them.

Everything You Need to Know About Kobalt Torque Wrenches
Operation
When tightening screws and nuts, for example, on your car or bicycle, considerable precision is required, given the importance of the mechanical parts involved. It is even the manufacturer itself that often indicates what the right tightening torque should be.
The torque wrench is just for this, to tighten the bolts to perfection, as it is recommended. With a standard ratchet wrench, it would be impossible. The two tools are very similar, but the performance – and the price – of the first are superior.
This does not mean that it is a tool reserved for professionals because the operation is simple, and everyone can use it successfully, even the less experienced.
There are basically two types: snap-on ones that, when the correct torque value is reached, emit a click, generally well audible, and at that point, they must be detached.
The torque is set by turning the knob down manually before starting to tighten. Other models, on the other hand, are digital and integrate a display that also warns with light signals, as well as sound.
Another type of torque wrench, much less common in truth, is the so-called dial or pointer, which is more difficult to use and which we will not consider in any of the reviews below.
Tightening Torques
Not all torque wrenches are created equal. The first thing you need to check before buying one is to check which tightening torques make it possible.
Some models are particularly versatile because they cover an extensive range. Others have very low torques ranging, for example, from 2-3 Nm (Newton per meter) to 20 Nm. Still, others start from 40 Nm to 200 Nm, and so on.
It is an essential preliminary choice for obtaining the best results based on the work to be done. For example, the best torque wrench for tightening screws and bolts of a bicycle is the one with low, indeed very low, tightening torque.
A wrench with too high minimum tightening torque is a wrong purchase, it may be unusable for your bicycle, while it will be useful for tightening the mechanical parts of a rim or engine of an automobile.
Performance
Compare prices and tightening torques but also pay attention to other aspects: if you are a professional, you will need a tool made with quality materials that can last over time and not stand even if used very often.
In such a tool, the precision that the manufacturer itself should indicate is also essential: a tolerance of ± 4% is a good result, but if you need even higher performance you could opt for models that guarantee a difference of ± 3% or even ± 2%.
The keys of the best brand could be for you those with clicks of 0.1 Nm, ideal for those looking for maximum precision.
Its Function
The torque wrench is used with the sockets and allows you to tighten screws, nuts, and bolts with the correct torque value. This value must be set before drawing; an indicator shows when the aforesaid amount has been reached, and therefore it is no longer necessary to exert force for the grip.
The Snap Torque Wrench
This type of key is the most common and precise. To set the torque value, generally, you need to rotate the key handle or act on a maneuver rod. The amount is indicated on the body of the key or on a dial.
Once the data has been set, it must be locked to avoid accidental changes. At this point, the compass is mounted on the attack. A click indicates how much the previously assigned tightening value has been reached.
The Dial Wrench Dynamometers
This type of key, according to many experts, cannot boast the same precision as the click key. Legends of this type, at least in their most current version, have two parallel metal bars: one acts like a union between the handle and the square attachment, where the compass is to be positioned. The second bar is connected to the head and acts as a pointer on a graduated scale.
When applying a force by holding the handle of the key, exercising the classic movement from right to left to tighten the bolt, the second bar, that is, the hand does not move. When the user reads on the dial the achievement of the set value, he stops his action.
Now, if for any reason the user is not able to observe the dial, because the position does not favor him, he will have no way of understanding if the set value has been reached because, unlike the release key, there is no device that inhibits tightening.
The Quality of The Tool
As the reader will have understood, a snap torque wrench is preferable, but it is not enough. It is essential that the key is of good quality. This means that the materials must be of a good standard as well as the mechanisms.
