Socket heads (6 points)

Number of hex sockets included in the tool kit.

All end heads are accessories for a collapsible tool; during operation, they are mounted on a ratchet, wrench or other similar device. The head itself has the appearance of a characteristic “cap”, which, during operation, is put on a bolt, nut, etc. This design, among other things, allows you to work with parts located in recesses and some other hard-to-reach places that cannot be reached with open-ended, captive or split keys. And compared to a set of classic socket wrenches, the holder plus socket set takes up much less space, providing almost the same functionality.

As for the 6 faces, this type of socket head is the most famous and widespread, because. most modern nuts and bolts have this shape.

Socket heads sizes (6 points)

Working size range of hex sockets (see above) supplied with the kit. This parameter allows you to evaluate how the heads fit the dimensions of the fasteners with which they are planned to be used.

Socket heads (12 points)

Number of dodecahedral sockets included in the tool kit.

All end heads are accessories for a collapsible tool; during operation, they are mounted on a ratchet, wrench or other similar device. The head itself has the appearance of a characteristic “cap”, which, during operation, is put on a bolt, nut, etc. This design, among other things, allows you to work with parts located in recesses and some other hard-to-reach places that cannot be reached with open-ended, captive or split keys. And compared to a set of classic socket wrenches, the holder plus socket set takes up much less space, providing almost the same functionality.

Specifically, the 12-sided type of socket heads is considered more versatile than the hexagonal one: it makes it possible to work with both classic hexagonal fasteners and, in fact, twelve-sided ones. In addition, to hook the next face, it is enough to rotate such a tool by only 30 ° when rearranging (whereas for 6-sided nozzles this figure is 60 °, and in cramped conditions there may not be room for this). On the other hand, 12-sided parts are quite rare, and when working with hexagonal parts, the contact area is small, which increases the risk of stripping edges and reduces torque.

Bits

The number of bits supplied with the tool kit. A bat in this case is called a working nozzle, which plays the role of a screwdriver tip; in fact, they are most often used with screwdriver handles (see above).

Many types of splines (slots) are used in modern fasteners — starting with the well-known straight, cross-shaped ( Phillips and Pozidriv), Torx sprockets and ending with exotics like Torq-set (a cross with lines shifted from the centre), Pentalobe (with five ledges), etc. .P. In addition, the size of the slots can also vary, and in many cases, tool matching in size is very important. Accordingly, the more bits supplied with the set, the more versatile it is, the higher the probability that it will contain a nozzle of the desired type and size. However, the specific list of bits in the kit also does not hurt to clarify — in order to make sure that it has all the varieties you need. In the characteristics of individual sets, these data are given in the paragraph "Bit sizes" (see below).

Extension

The type of extension included with the tool kit.

Extensions refer to "intermediate" devices, if necessary, installed between the main tool (like a screwdriver handle, see above) and the working nozzle. As the name implies, they allow you to increase the length of the working part of the tool — for example, to get to hard-to-reach places. Here are the main options for such devices:


Hard. Rigid rod extension. It does not give such freedom of action and the ability to get to hard-to-reach places as flexible (see below), but it is considered more reliable, allows you to develop great efforts (often the same as when working without an extension cord) and even allows the use as an improvised lever. Some rigid extensions may also have a crank function (see above).

Flexible. An extension in the form of a flexible tube, usually made of a metal spiral. Such an extension, like a universal joint (see above), allows you to position the nozzle at an angle to the axis of rotation of the main tool — while the range of such angles is much wider (in some cases they can reach 180 °), and the long length and high mobility of the device are even more expands freedom of action. The disadvantage of flexible extensions is less suitability for work with greater efforts than the rigid ones described above.

— Rigid/flexible. This option is indicated for sets equipped with both types of...extensions described above. This makes it possible to choose an option depending on the specific situation.

If there are several extensions of the same type in the kit, they, usually, differ in the size of the attachment (see "Landing square").
