Features of articulated wrenches

The features of hinged wrenches should be known to everyone who works with various tools in everyday life and at work. Now they produce a reinforced wrench with a hinge of 600 mm and 750 mm, models with a 1000 mm long handle and other wrenches for socket heads, and all these devices have their own nuances. They must be applied according to strict rules.

Many technical manipulations are needed in the most unexpected places and cases. However, a special tool allows you to successfully resolve all such incidents. The standard set of tools for any motorist should just include an articulated wrench for socket heads. Externally, it is a handle with a rigidly fixed rigging. Such a device is necessarily made from strong grades of metal.

The size of the knob can vary greatly. Its geometry is also not always the same. That is why articulated wrenches are actively used not only in car repairs, but also in construction work. In the second case, the tool rotates other devices that have a fixing or cutting task.

The 1/2 hinge collar is supplied by a large number of manufacturers. Therefore, choosing such a product is not difficult. Noteworthy, for example, the model "Standard"... It has 39 teeth. The working part is made of tool steel, and the handle is rubberized.

An alternative is the DR 300mm Airline AT-HDR-12... Its working area is made of high quality steel alloy (with the addition of chromium and vanadium). Hot forged metal lasts a long time. The topcoat not only increases overall wear resistance, but also makes cleaning easier. The mass of the crank is 0.55 kg.

The reinforced wrench type can also be 1/2 in size. This is exactly what the Tevako TVK-08021 model is.... It is optimized for use in the most difficult-to-reach areas. The reinforcement of the structure makes it easy to create the required torsional moment. The main structural material is chromium-molybdenum steel.

An alternative reinforced fixture is available from Hans. The main nuances of version 4700 N:

• professional appointment;
• length 380 mm;
• total weight 0.68 kg.

Among the models, the products of "AutoDelo" deserve 3/4 attention.... This is an elongated articulated wrench. Its length is 930 mm. For manufacturing, a chrome vanadium steel grade is used. It is especially emphasized in the description that the coating with insulating properties is not applied, and the surface has a matte sheen.

Choosing a 3/8 modification, you should take a closer look at the version from "Standard". It has 39 teeth. This ratchet is made up of tool steel. The handle contains a rubber part inside. The container (plastic suspension) should also be noted.

It is also useful to examine the 1000 mm wrenches. They, in addition to the long handle, contain a 1-inch articulated landing square. The special cast rod in the Force 80181000 model allows for particularly strong force.

Such a long device is not always required. In some cases, the 430 mm model from Force helps... True, there is very little reliable information about her. It is known that such a device is designed for size 1/2. In the reviews, they invariably note the strength, convenience and high quality of such a product.

If you need to choose a crank with a length of 600 mm by 1/2, then "Cobalt 649-905" can be a good solution.... The official description emphasizes the strength and durability of such a tool. It can serve for a long time. Dielectric processing, as in other cases, is not provided.

The 750mm half-inch wrench is sometimes reinforced. This is the typical Licota AFT-B1230 product. Its mass reaches 1.625 kg. The official description even indicates the total volume of the product - 0.00054 m³. There are, of course, a number of other solutions, but for obvious reasons it will not be possible to describe everything.

Even the best tool must be used correctly. The gates are selected taking into account the type of fastening being serviced. In many cases, not excluding manipulations with any one car model, there can be a significant difference between them. Articulated wrenches can be turned at any desired angle, which significantly expands the possibilities of manipulation. There are also such important nuances:

• it is articulated products that should be used when working with any fragile nodes;
• when choosing, one must not forget about the size of the landing square;
• the permissible level of loads should also be taken into account;
• the material is selected according to the conditions of the planned operation;
• rubberized handles are more comfortable, but all-metal handles are better protected from the spill of gasoline or engine oil;
• when reading reviews, you need to pay attention to wear resistance;
• articulated wrenches of domestic production are cheaper than imported ones, but they are usually not inferior in work.
