A set of hand tools is a set of devices necessary both in everyday life and when performing specific work on the repair of machinery, equipment, transport.

The usual set includes packaging - a box, case or other variety with all the contents: a tool, keys, additional accessories to them.

Depending on the filling of the package, the sets are divided into types:

• professional series: universal, automotive or special kits;
• household series: for homework, amateur tools for motorists, radio technicians and the like;
• series of one kind of tool (for example, wrenches), but different sizes.

Each set must include keys in one combination or another. Most often, there are kits, which are a compact plastic case, the internal space of which is planned in such a way that each element has its own strictly defined place. The complete set of a standard case, as a rule, includes:

• wrenches of several types with different parameters;
• ratchet with heads, the size range of which in most cases ranges from 8 to 24 mm;
• bits.

Many are familiar with conventional wrenches, but they are not always convenient when working in confined spaces.

The ratchet is a comfortable chrome-plated steel grip with a ratchet head at one end. A special mechanism allows, without making any special efforts, to unscrew any fasteners in a very narrow place.

Ratchet wrenches can be classified into the following types:

• cap - similar to similar nut ones, but thanks to the ratchet mechanism, they are convenient for working in hard-to-reach places;
• for socket heads - very much in demand in car repair and maintenance services;
• with hinge, installed between the head and the handle, which allows you to use the tool at any angle;
• combined with moving head for operations with threaded connections, access to which is limited.

Devices with a ratchet mechanism are irreplaceable helpers both in everyday life and in professional fields.
