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 (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.

Bit sizes

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.

Hex wrenches size

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

Dimensions

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.

Weight

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.
