Total number of items

The total number of core items included in the set.

In this case, the main items are all devices that are directly used during work: non-separable tools (traditional wrenches, hammers, pliers ...), elements of collapsible tools (for example, a ratchet for removable heads and 5 such heads will be considered 6 units) , as well as accessories (such as extensions or universal joints). Additional accessories — such as lights — may or may not be included in this count, depending on the manufacturer; however, there are usually few such accessories, and they do not fundamentally affect the total number of items.

The most modest modern tool kits include up to 25 units. However, such kits are very popular — they are inexpensive and at the same time can be very versatile. 25 – 50 items is still quite a small number, 50 – 75 pcs can be called an average, 76 – 100 items are more than average, and the most extensive modern sets can include 100 – 150 items or even more.

The general rules for choosing this parameter are obvious: a more extensive set, usually, is more multifunctional, but more expensive, weighs more and takes up more space. It is also worth bearing in mind that with a similar number of items, the specific assortment of these items in differ...ent sets may be different; so when choosing, it is worth specifying not only the number of tools, but also their specific composition.

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 (E-profile)

The number of E-profile sockets supplied with 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, this type of heads has a working part in the form of a six-pointed star, which is why such nozzles are also called “asterisks”, “Torx” or “internal Torx”. The latter option is used to avoid confusion with Torx keys (see above): the working part of such a key (“external Torx”) has the form of a star-shaped rod, while in the end head the working part has the form of a recess with similar outlines. As for the use of such heads, when used with “native” fasteners, the E-profile allows you to work at high forces without much risk of breaking the edges; and fasteners are used for such tools, in particular, in cars.

Socket heads sizes (E-profile)

Working size range of E-profile 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.

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).

Adapter

An adapter for docking seemingly incompatible elements from a set. For example, socket heads with an unsuitable landing square on a ratchet, screwdriver handle or in a drill driver. The adapter provides full-fledged work with all the required list of tools from the set.

Combination wrenches

Number of combination wrenches supplied with the kit. Note that some modern kits include only combination wrenches, without any other fixtures or accessories.

Combined are called bilateral keys, on which different types of working profiles are located on different sides. Most often, such keys combine open-end and cap profile, very rarely — open-end and end. The technical features of each of these types are described in the corresponding entries in the glossary. However, anyway, the working dimensions of the profiles in one tool, usually, are the same — this allows, without changing the key, to choose the best option for a specific part, depending on the features of the work. As for the quantity, it is worth considering here: sets with the same number of keys of the same type may differ in the specific sizes of these tools. Such nuances should be clarified before buying separately.

Split ring wrenches

Number of split wrenches supplied in the kit. Note that some modern kits include only split wrenches, without any other fixtures or accessories.

According to the shape of the profile, such tools are a cross between open-end and box wrenches (see above). In fact, the working part of the split key looks like a cap ring, from which a small part was cut out, turning this ring into “horns”. However, such tools also differ from open-end wrenches: the “horns” mentioned are clearly bent towards each other, and the surface in contact with the fastener does not have the shape of the letter “U”, but of a pronounced hexagon or asterisk.

Thanks to this design, split wrenches provide a much better distribution of force over the fastener than open-end wrenches, and at the same time do not have such restrictions on use as box wrenches. To illustrate, we can cite the use of such a tool in a car service. It is split wrenches that are considered the best option for servicing brake systems, fuel and oil lines, etc.: they allow you to securely tighten fasteners and at the same time work without problems in hard-to-reach places and with hose attachments where box wrenches would be useless.

Note that most often modern split wrenches are made double-sided, with working profiles of different sizes at different ends. As for the quantity, it is worth considering here: sets with the same number of key...s of the same type may differ in the specific sizes of these tools. Such nuances should be clarified before buying separately.

Wrench sizes

Dimensions of the wrenches supplied in the set. Specified as a range — from the minimum to the maximum size. In this case, the specific distribution of different types of keys over the range may be different. An example is the following set: 17 open-end wrenches, 5 box wrenches, size range 6 – 24 mm. In such a set, box wrenches are almost guaranteed not to cover the entire range of sizes, but for open-end wrenches, this is quite likely. Such details can be specified separately.

Also note that a wrench size of 24mm or more is considered quite large for today's general purpose tools. However, on the market you can find sets that include wrenches for 27 mm, 30 mm and even 32 mm.
