Comparison STELS 14117 vs STELS 14105

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).

The dimensions of the entire set, namely the case, lodgment, cassette, etc. storage accessory (see paragraph above) with tools installed inside. Allows you to understand how much space the model will occupy and whether it can be placed in a complete set in one place or another.

The total weight of the tool kit. Indicated with a case, stand or other storage/transportation device (see Tool Storage). First of all, you should pay attention to this parameter if you plan to often carry the kit over long distances — the lighter the weight, the easier it will be to do. At the same time, extensive sets inevitably turn out to be weighty.
