It is very difficult to get by with just one tool in everyday work. Combination wrench sets can come to the rescue. However, it is necessary to choose such kits carefully, taking into account the maximum of subtleties and nuances.

Selection Tips

The main thing to consider when choosing is the size of the supplied tools. A combination key is called a key that has 2 heads - an open-end and a cap. This solution allows you to cope with most tasks. You need to understand what a set of keys can be used for:

• for household purposes;
• for servicing bicycles, cars;
• in construction and repair;
• in working with agricultural machinery;
• in fitting and assembly manipulations;
• in working with plumbing fixtures.

Depending on this goal, it is necessary to select the composition of the instrument, its variety . Any set will definitely have wrenches. The spanner and ratchet head of the wrench can be used equally well. However, the ratchet option allows you not to remove the key every time from the connection, but to use it after rearrangement. Therefore, in most cases, they choose a combination of open-end wrenches and box wrenches or a purely mixed ratchet tool.

The advanced sets (including 22 or even 26 pieces) contain keys from 6 to 32 mm. The simplest sets, consisting of 6 keys, usually cover the sizes of 0, 8-1, 9 cm. Even for domestic purposes, extended sets (12 or 15 devices of various sizes) are more justified. But it is not only the number of items in the set that is important. We must also take into account what they are made of.

Quality tools should be made from chrome vanadium steels. In addition, external protection with zinc or another anti-corrosion agent is also required. Usually, the full chemical composition is painted on the product itself. If this is not the case, then it is better to refuse the purchase. You should also inquire about the brand of the product. First of all, you need to trust the products of leading companies. It is useful to pay attention to the bag or case. Depending on personal preferences, they choose:

plastic container;

steel suitcase

soft fabric cover

Specific proposals

A modern set of spanners with a ratchet and a hinge can be a very valuable acquisition. This set contains 6 pcs. mixed keys. Their dimensions are 0, 8, 1, 1, 2, 1, 3, 1, 4 and 1, 7 cm. Each key contains:

horn head;

frame

annular active part

spring part

The kit is sold to consumers in a plastic container. The part of the annular element located inside the housing contains 72 teeth. The geometry of each of the teeth is chosen so that due to the pawl, the part rotates in only one direction. To move it in the opposite way, the key must be turned over .… Disassembly is structurally impossible.

Thanks to the hinge, it is possible to change the inclination of the working parts by 180 degrees. The described wrenches allow the nuts to be loosened without permanent repositioning. This property is especially important in confined spaces. But gradually the dog, and the teeth themselves, will wear out. As a result, the key may "slip".

The ratchet in this tool kit has no lubricant inside. Therefore, the ratchet mechanism will wear out excessively. It is also worth considering that there are no keys for 1, 1, 1, 5 and 1, 6 cm. It is reasonable to pay attention to the OMT82S kit supplied by the Taiwanese company Ombra . This company knows a lot about the production of professional-grade hand tools - there are no problems with their sets.

This kit is designed to work with a wide variety of fasteners. The outer shell of all instruments is covered with three layers of specially selected nickel and chrome compounds. Such a mixture is guaranteed to exclude the slightest corrosion phenomena.

A common mistake is the opinion that it is impossible to find a quality kit for reasonable money.

If you need a set of shortened keys, it makes sense to choose KING TONY 9-1282MR . It includes 12 instruments. With the help of such devices, it is easy to carry out installation, repair or dismantling work on a variety of mechanisms and units. The designers made sure that the tool could be used in a confined space.

Delivery takes place on prepared polymeric cradles suitable for completing tool trolleys.

Licota ACK-B1004 can also be a good choice in some cases . This set includes combined open-end wrenches of 2, 4-3, 2 cm in size. Nine of these tools are placed in the cradle. The total weight of the collection is 5, 345 kg. It comes with a 1 year warranty.

The manufacturer claims that this kit is suitable for mounting and dismounting threads during repair work. The original ACK-BCOVER cover is optional . Thanks to her, you can turn the lodgement into a typical tool kit. It is convenient both on the road and in the absence of instrument cabinets. In addition to general recommendations, it is important to know additional subtleties.

What tools are supplied?

Combination wrench sets invariably contain traditional carob devices … A pair of horns extend from the handle. The distance between them is equal to the size of the nuts and bolts. In most cases, standard open-end wrenches are equipped with arms of various sizes at the ends. The head is located at an angle of 15 degrees in relation to the longitudinal axes of the handles.

Some models have a tilt of 75 degrees . Often heads are combined with different angles, but the same size. It is necessary to use an open-end wrench if it is possible to get to the nut only from the side. In all other cases, a more practical solution is a spanner . It's just a ring that duplicates the geometry of the nuts and bolts from the inside.

Least torque to turn fasteners when using a wrench with 12-sided inner profile … The hexagonal version is much better suited for "power" work. Sometimes there are designs similar to an open-end wrench, only with rounded edges. There is nothing unexpected here: just a slot is made in the ring device so that you can get to the nuts not only from the ends.

There is also end - including articulated (allowing to work in different positions) keys. Among the end tools, one more often distinguishes angular and tubular constructions. If it is not indicated what is combined with, manufacturers mean horn and cap elements. A convenient option is when their heads converge at an angle of 90 degrees. Regardless of which end you grasp, the palm will rest on the opposite edge.

Quite often, for working with hex fasteners, it is used dynamic profile tool … Typically, these keys are in the open-ended format. The role of the dynamic profile is to exclude violations of the nut faces. As a result, the operation of both tools and fasteners is maximized.

Force should not be used when using any combination wrenches.
