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.
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.
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.

Slotted
Screwdrivers with flat tips, originally designed for a slot in the form of a slot. Note that such tips are quite versatile, they can be used with cross slots, and even with asterisks — the only thing is that in such cases it is impossible to apply great efforts due to the high probability of tool breakage.
Cross-recess
Screwdrivers with tips designed for cross slots. Note that flat screwdrivers also work with such slots; however, it is still better to use “native” tools — they distribute the load more evenly and allow you to apply great efforts without the risk of tearing the edges of the slot.
