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.

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.

Tap wrench

The number of knobs supplied with the tool kit.

The collars are a composite tool and are used exclusively in combination with various nozzles, and sometimes with bits. As the name implies, they are designed to rotate such nozzles; moreover, the common point for all the knobs is that the nozzle is located perpendicular to the handle — this provides a large lever arm length and high torque with a relatively small effort on the handle. The specific design of the collars may be different. One of the most popular options is T-shaped devices, which can also vary: the nozzle mount can be located in the centre of the handle or closer to one of the edges, it can be movable or fixed, removable or non-removable, etc. There are also L-shaped collars, similar to socket wrenches (see above) with interchangeable nozzles; cardan, in which the mount is located at the very end and can be rotated to a selected angle, etc. If there are several wrenches in the kit, they usually have the same design, and the main differences are in the length of the handles, as well as the types and sizes of attachments for nozzles.

Note that in some sets, the role of a wrench can be played by a rigid extension (see below), equipped with a removable mount for the nozzle, and when such a mount is installed, it turns into a wrench handle. Such a device, when calculating the total number of units (see above), is considered as one item, although it performs two...different functions and is indicated in our catalog as both a crank and an extension.
