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.

Square drive size

The size of the "seat" for which the socket heads included in the package are designed (see below), in other words, the size of the square hole on the back of the head used for installation on a ratchet, wrench or other similar tool. Accordingly, the tool for working with heads supplied in the kit has the same dimensions of the landing square; and in the absence of such tools in the kit, data on the size of the heads will be useful for its selection.

There is a generally accepted standard for these sizes, providing for the designation in fractions of an inch — from 1/4 "to 1". Thanks to this, heads and tools from different sets can be quite compatible — just matching in size is enough. Most often in modern hand sets there are options in 1/4 "and 1/2", a little less often — 3/4" and 3/8". Some sets include several variants of the landing square at once.

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.

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.

Bit holder

Auxiliary bench tool that adapts the fit of the bit to the drill chuck. One end of the bit holder is fixed in the chamber, the other — in the shank of the bit, which allows you to work with any type of equipment. It is used when performing work on screwing fasteners in spaces where it encounters certain difficulties. Many bit holders have the ability to magnetically hold fasteners.

Hex wrenches

The number of hex wrenches supplied in the kit. Note that some modern kits include only hex wrenches, without any other fixtures or accessories. It is also worth emphasizing that in this case we are talking about the simplest hex wrenches. Imbus tools — similar in purpose, but different in design — are highlighted in our catalog in a separate category (see below),

Keys of this type usually have the form of L-shaped handles made of a hexagonal rod. Thus, the user can work with both the short and long side of the key; in the first case, the long part of the letter "G" works as a lever, providing a good effort, in the second — it plays the role of an extension. And such tools are used for bolts and other similar parts with a hexagonal cut in the cap. Such splines have a number of advantages over the classic straight and cross splines (in particular, better tolerating high torques), which makes them quite popular — in particular, in bicycles.

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.

Imbus wrenches

The number of imbus keys included in the tool kit.

Such keys are a type of hex key (see above). In fact, even ordinary hex keys are often called “imbus” (from INBUS, the trademark under which they were once patented). However, in our catalog, only those hex keys are classified as imbus keys, the design of which includes a characteristic rounded tip, similar to a ball soldered to the end of the key. Such a tip allows you to tilt the wrench at a certain angle relative to the axis of rotation of the fastener when working, which can be very convenient when working in hard-to-reach places.
