Specific options
The ratchet spanner sets from Delo Tekhniki have very good performance. One of these sets includes 7-24 mm tools. The set includes 14 pieces. Judging by the reviews, during the year of active operation, the products do not lose their positive qualities. The described set is quite sufficient for everyday work with the car.
Delo Tekhniki's products compare favorably with the old models made in the 1980s. It is performed according to a combined scheme, when one side is a cap and the other is a carob format. A ratchet is mounted on the cap edge, thanks to which dismantling and assembly are simplified as much as possible. Keys do not even bend during very strenuous work, including using the "key and elongated pipe" method.
Another set contains 9 keys with sizes 8-22 mm. All of them are also made according to the combined scheme. The fracture resistance is increased due to the use of reinforced profiles. Sponges of increased thickness are made on them. The fixing of the keys on the nuts is as tight as possible, which almost completely eliminates the breakdown.
When choosing sets of 6—32 mm, it is appropriate to pay attention to Airline Torx spanners. First-class chromium and vanadium steel is used for their manufacture.
Its long-term operation is ensured by the hot forging technology. The final stage of processing is the application of chrome plating. In addition to increasing wear resistance, this coating helps to reduce contamination.
It is useful to pay attention to the King Tony 1712MR set. The twelve tools included in the kit fit into a soft package that can be conveniently hung on a workbench or on a wall
The total weight of the kit is 3.75 kg.
As for the sets of 10-27 mm, everything is very difficult here: it is almost impossible to choose just such sets. A good replacement is NORGAU N2-011 (of 11 instruments). The set is supplied in foam plastic lodges. The size of the keys ranges from 6 to 32 mm.
The presence of "unnecessarily small" devices cannot be considered a minus, because in everyday life it is often necessary to work with them. In most cases, the sets include standard size keys. Elongated devices will most likely have to be purchased separately. It is advisable to choose them in the same way by material and brand, as well as whole sets.

Selection recommendations
Inexperienced auto mechanics or amateur repairmen should thoroughly understand this topic. An error can lead to the fact that the money given for 12 pieces. keys will be "wasted".
As for the number of copies in the set, 6 keys will be enough for non-professionals for occasional works.
For specialists, kits of 15 or more tools are much better suited. But usually they themselves can pick up what they need. Of the materials, structural steel with the inclusion of chromium, molybdenum, and also vanadium is considered the best solution.
Before giving preference to the products of this or that manufacturer, you need to pay attention to independent reviews. Certainly deserve attention Ombra, Arsenal, Makita
It makes sense to buy Chinese products only as a consumable. They are not suitable for any lengthy work.
Cloth or plastic products are cheaper, but less practical.
Peculiarities
There are many types of wrenches that are widely used in practice. The main requirements for each product are operational reliability and the ability to unscrew fasteners anywhere, even if it is difficult to access.
As a result, along with an increase in the applied force, its uniform distribution occurs.Therefore, damage to hardware is completely excluded. There are models in which, instead of one grip, 2 are installed. It is customary to divide spanners into three main groups:
- flat (in which the working segment and the handle occupy a common axis);
- bent (with a deviation of the working segment from the axis by 15 degrees);
- curved (with a bend of various sizes).
