Comparison JONNESWAY S04H52460S vs Force 4941R-9

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.

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.

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.

Number of dodecahedral sockets included in the tool kit.

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.

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).

Varieties of bits (see above) included in the set.

Note that this paragraph specifies not just the size, but also the type of slot for which this or that bit is designed. This type is indicated by a letter index followed by a number describing the size — for example, SL5. Here are the most popular designations found in modern bits:

— SL. Flat bits for straight slot. The size is indicated in millimetres.
— Ph. Classic cross bits. The size is indicated by a conditional number.
— P.Z. Bits for a modified cross slot with improved engagement, have additional edges. The size is indicated by a conditional number.
— TX, T. Torx bits, with six-pointed sprocket tips. The size is indicated by a conditional number.
— H. Hex bits, with hex tips. The size is indicated in millimetres.


If there is more than one bit of a certain type in the set, the number is specified after the designation, for example, PH2x2.

The number of ratchet wrenches in the toolbox. The name of such tools comes from the ratchet mechanism installed in them, which emits a characteristic crack during operation.

First of all, we emphasize that the term "ratchet wrench" in this case means a composite tool — in the form of a handle with a seat for interchangeable nozzles (for example, socket heads of one type or another — see above). Do not confuse such a tool with more traditional wrenches that have similar equipment (for more on such wrenches, see "Ratchet (ratchet)"). Nevertheless, the meaning of the ratchet mechanism in this case is absolutely the same: thanks to it, the ratchet rotates the fastener only when turned in one direction, while the captured part remains motionless during the reverse movement. Thus, for constant rotation of the fastener in one direction, it is enough to swing the tool back and forth — this is much more convenient than periodically rearranging it or turning it full 360 °. The change of direction is usually carried out by a switch built into the ratchet.

Several ratchet wrenches included in one set, usually, differ in the size of the landing square (see above) and the length of the handle itself.

The number of universal joints supplied with the tool kit.

First of all, we emphasize that this device should not be confused with wrenches that have a cardan. For more information about them, see paragraph "Gimbal" above; here we are not talking about an independent tool, but about an auxiliary device that is installed as an intermediate link between the main tool (for example, a crank, see above) and a working nozzle. Such a device allows you to position the axis of rotation of the tool at an angle relative to the axis of rotation of the nozzle with fasteners; this can be very convenient, in particular, when working in hard-to-reach places where there is not enough space for a classic "straight" tool.

Several universal joints, usually, are provided in sets with several options for the size of the landing square (see above) — one joint for each size.
