The best torque wrench for a passenger car: rating, which model to choose, comparison table

Types of torque wrenches for cars

There are several types of devices:

1. Arrow is the most common type. It is characterized by low cost and simple design. However, in terms of technical characteristics it is inferior to other models. The error is 10%, the maximum tightening level is 280 N.m. Switch options are used for light routine work.
2. Click - with a preset maximum, which is triggered when the tightening is too strong. The error is 3-5%, the tension force is from 40 to 360 N.m. The devices are used in domestic or industrial environments.
3. Electronic - characterized by better performance. The error does not exceed 1%. There is an electronic scale reflecting the degree of tightening.

You can study the parameters of devices using the table:

Which one is better in design and execution?

4 types of keys are considered the most reliable; it is worth studying the main characteristics of each of them. This will help you understand which device is best to choose, taking into account the specifics of the work.

Limit type adjustable

The product is characterized by the simplest design. The user sets the torque limit. When this value is reached, a click appears, indicating the need to stop tightening. The handle is equipped with an adjustment mechanism and a scale. More expensive models are characterized by high measurement accuracy. When purchasing such a key, you should choose devices with a removable square. In this case, you can install any heads.

Switches

The device operates on the principle of a dynamometer built into the body. The device is equipped with an indicator arrow located in the upper part. There is also a square for installing attachments or heads.

The tool has low measurement accuracy, so it is not advisable to use it when repairing a car.

An arrow key is best used in construction or other similar industries.

Digital

This device is equipped with many additional components. There is a built-in memory, the device can be connected to a computer. A wide range of settings allows you to choose the desired option. The design of the key includes a square, a handle, and a working part. The rod contains a mechanism that calculates torque and sends data to the screen. Digital devices are calibrated automatically or manually.

Key adapter

The device is equipped with a mechanical drive connected to a ratchet. The adapter has a head or nozzle. To configure the device, buttons and a monitor are used. The adapter is accurate and versatile, which is considered its main advantage.

Options for measuring wrenches with ratchets

Torque wrench included with a set of sockets

Ratchets in car torque wrenches can be removable or non-removable. Removable heads allow you to use one handle for different sizes of nuts, making the tool more versatile. In addition, there are removable ratchets that work in two directions, both on the left and on the right thread. The direction of rotation is set using a special three-position lock switch. This option is more expensive compared to keys with a fixed head.

Fixed ratchet wrenches are usually sold as a set of three tools, designed to accommodate a range of nut sizes. However, you can choose a separate wrench with a suitable range of forces. To expand its range of application, you can use multipliers, which are a regular gearbox that increases or decreases the tightening force transmitted to the head.

How to pick and choose?

Each has many different benefits and amenities to consider before making a purchase.

Below is a list of parameters that you need to rely on when choosing.

• Torque range;
• Connection size;
• and a method of notifying that the required effort has been achieved;
• and units of measurement;
• Material of manufacture;
• Size ;
• Availability of a case;
• Convenience of setting torque and reading the scale;
• Handle material;
• Warranty, service center and availability of spare parts;
• Directions of action;
• Availability ;
• Reset button;
• Articulated head;
• Country of Origin;
• Price.

Having listed all the parameters that need to be paid attention to, we will try to talk in more detail about each point in order to decide which one in a particular case to solve the problem.

Torque range

This parameter determines the range in which it works. The range of a tool is closely related to the meaning that needs to be conveyed in any given use.

in total they operate within 25-85% of the main range.

For example, it is necessary to tighten a threaded connection with a force of 30 N/m. with ranges of 6-30 N/m 16022030 and 20-110 N/m 16033110 can cope with the task. So what is 16033110 with a range of 20-110 N/m, since the required force “does not lie” at the extreme value of the scale, which means that the tool spring will not stretch so quickly. Yes, the second one, unlike the first one, will not be able to work with smaller values, but for less effort you can purchase a second one, for example, with a range of 5-25 N/m 16032025.

Therefore, do not select an instrument that will primarily be used at the lower or upper end of the scale. You might be tempted to do this to save money, but the torque output could seriously outweigh any savings.

Connection square size

Have you ever purchased a tool regardless of the size of the attachment? Choose according to the size of the inch assembly tool (sockets, extensions, etc.) that you most often use (1/4, 3/8, 1/2, 3/4 or 1 inch). In some cases, adapters may be required.

They also exist with specific drive sizes: 9x12mm and 12x14mm. These are used together. Open-end wrenches allow you to tighten fasteners between the parts being connected, and are also capable of working with nuts on high studs. Torque wrenches for air conditioners are an example of using such a tool. Therefore, the choice directly depends on the specifics of the work performed.

and a method of notifying that the required effort has been achieved

There are many models from which you can choose. Here are the main ones:

• Switch;
• Snap;
• Digital;

The first type is more used by amateurs or in garage workshops, where the high ones are not regulated, and are the least accurate of all. The force must be controlled by an indicator at a specific point in time, which is not very convenient, since it is always necessary to monitor. The start of the controlled range of the torque wrench from 0 Nm is another feature of these models.

used in most professional workshops because it uses to indicate when the required preset torque has been reached.

However, some people prefer electronic torque wrenches because the display can track the force being applied at a specific point in time. Also, when the set torque is reached, it emits a sound signal that sounds louder than.

and units of measurement

Different models have different torque transmission. The most important are the models, then and only then.

supplied with a factory calibration certificate indicating the date and . Therefore, the tool should be calibrated according to the maintenance schedule to maintain factory specifications. Verification must be carried out annually or more often, depending on the frequency of use.

The instrument may have scales with multiple torque measurement values. Before purchasing, be sure to look at what values ​​are used for measurement in your area so that you do not need to convert to the required values. Basic torque values:

• N/m (Newton per meter);
• Kg/m (Kilogram per meter);
• lbf/ft (Foot-pounds).

Unit conversion:

• 1 Kg/m ~ 10 N/m;
• 1 kg/m ~ 7.2 lbf/ft.

Material of manufacture

Most are made of metal with plastic or rubber parts/inserts. The more plastic a tool contains, the more carefully it should be used and stored. As a rule, plastic is located in the handle area, increasing the convenience and ergonomics of use.

Size

Take this into account if you need to carry out work in hard-to-reach places. At the same time, you need to understand that the higher the torque range, the larger and longer the tool will be.

Availability of a case

It is worth choosing a measuring device, so it is necessary to exclude the possibility of falling, moisture and other possible factors of damage.

It is necessary to store only with the minimum torque set to avoid stretching the spring and to preserve the tool.

Easy to set torque and read scale

The tool may have different dials for setting or controlling torque.

If the model has, then the scales should be easy to read and the torque should be easy to set.

The scale should also be clearly visible and have a minimum value for dividing torque values ​​in order to achieve maximum torque transfer when transferring force to the fastener.

It can be set at the required moment using the buttons. Make sure the display has a backlight, which will allow you to work with the tool in dimly lit areas.

Handle material

Handles can be made of different materials and have different design features. As a rule, the handle is made of metal or plastic or rubber. There are ergonomic handles that have a special shape for the girth.

Remember that during use the tool may become dirty with any liquids, so it must have a handle that will not slip in your hands. For example, the metal handle has a special notch, and plastic and rubber handles are made with the addition of oil and petrol resistant materials.

In any case, to feel the comfort of the handle of this or that, you need to hold it in your hands.

Warranty, service center and availability of spare parts

The tool must have a warranty period, which is established by the manufacturer. To count on a warranty, you need to understand that it must be used strictly for its intended purpose in compliance with all operating requirements.

Check the warranty period of use and the availability of spare parts, first of all, repair kits for the ratchet mechanism. Pay attention to the presence of a service center, since a serious and responsible company not only sells, but also services torque tools.

Ratchet repair kits are available for most AIST and MASTER brand models. AIST also has its own service center, which provides repairs and maintenance, both warranty and post-warranty.

Do not use the tool as a tool for unscrewing fasteners. Use together with amplifiers, such as a trumpet, is strictly prohibited. Do not throw away the tool after work.

In addition to the warranty, models must have a factory verification, which indicates the date, where and by whom it was produced.

Directions for action

Most can transfer torque to fasteners that have . Therefore, if, due to the specifics of the work, it is necessary to tighten a threaded connection with, then it is worth buying models that can work like with, but these are more expensive.

Presence of a ratchet

The mechanism allows you to quickly tighten the fastener, since there is no need to rearrange the tool when tightening. If models have this feature, then they are deprived of this option.

Reset button

Some have a reset button for bench tools, such as socket sockets. This option allows you to quickly remove the attachment from the .

Articulating head

Allows you to work with the tool in hard-to-reach places. The head has a hinge that allows you to bend the tool in the desired position.

Country of Origin

Most brands presented on the Russian market are produced in factories in China and Taiwan. AIST

and
MASTER
are manufactured and tested on modern high-tech production lines of factories in Taiwan. How do those made in Taiwan differ from their counterparts in mainland China? Taiwanese keys have:

• A clear
  scale for setting the required torque;
• A characteristic loud
  signal when the set force has been achieved;
• Reliable
  spring and ratchet mechanism;
• Long
  service life.

Price

In many ways, it can play the highest role in the selection process. Once you've narrowed down your options based on the criteria above, you can worry about costs.

At the same time, you can simply choose the cheapest option, but you need to carefully weigh the other offers, as you may find that other options ultimately lead to a better purchase overall.

Criterias of choice

A torque wrench is purchased taking into account:

1. Torque. If the tool will be used frequently, it is recommended to take several products with different parameters. When a device is purchased for a particular type of work, they focus on the tightening indicator that is required in such cases.
2. The size of the square. In this case, take into account the type of fasteners for which the selected device will be used.
3. Display method. Electronic options emit light and sound signals. When purchasing a simpler device, you will have to adjust the tightening yourself.
4. Measurement error. The lower the percentage, the better.
5. Device dimensions. It is not recommended to buy compact devices. Their operating ranges are limited, and it is more difficult to unscrew fasteners with such keys.
6. Case material. Tools must be made of durable metal. This is the only way to firmly tighten the bolts or nuts.
7. Handle material. Metal elements are considered more durable. However, such a handle constantly slips out, which complicates the work. The best option is metal products with rubberized inserts.
8. Ease of reading the scale.
9. Direction of movement. This point is worth considering for left-handers, since most instruments are designed for the right hand.
10. Ratchet included. Not all devices are equipped with such components. Therefore, it is worth checking out the completeness of the device before purchasing.
11. Reset button location. Ease of use is taken into account when evaluating this parameter. The location should prevent accidental pressing during operation.
12. Availability of attachments. The more components, the better. Moreover, each attachment increases the cost of the set.
13. Storage case. A case is optional, but it helps keep your tools handy.
14. Manufacturer's warranty. Its presence makes it possible to replace the device in case of premature failure.
15. Presence of service centers in the city. This allows the user to access instrument settings.
16. Maintainability. If there are no spare parts on sale, you should refuse to purchase the product.
17. Country of origin. Preference is given to cheaper Russian models. German and Japanese devices are considered to be of the highest quality.

How to choose

The choice is based on the above parameters. Most importantly, you need to understand what range is needed for the work and how significant the work being performed is. Let's say, when working with cars, you need to choose some models, and when working with trucks, others. It all depends on the size of the threaded connection for which it is selected. Although it must be said that many models are suitable for use in passenger cars, commercial vehicles, and trucks. True, they are used for different units and components.

comparison table

The table helps you compare the characteristics of the best torque wrenches.

What is the error of torque wrenches

All torque wrenches, as a rule, have fairly high accuracy. Most modern models have an error of no more than 4%, which indicates their fairly high accuracy.

However, you should know that the accuracy of some professional models of torque wrenches can reach 99%. Therefore, if you need a high-precision tool for connecting “capricious” equipment, then this nuance should definitely be taken into account.

Tips and tricks

A properly selected torque wrench helps you perform car repairs easily and efficiently. If you need to purchase the ultimate option, choose BERGER BG-12TW. With a limited budget, switch models are purchased, for example KMSh-140 NIZ 2774-140. If the cost of the product is not important, the best option is a device of a special design - JTC 4933.

How to use a torque wrench?

Depending on the type of tool, the operating instructions may differ. For example, click-type models should be set to the minimum value at the end of work to weaken the adjustment mechanism. We will describe the main nuances of how to properly use a torque wrench, which are suitable for any model of device, regardless of type:

1. It is not recommended to use this tool to unscrew nuts, otherwise you may lose settings or break the mechanism.
2. Do not set force values ​​beyond the setting limits.
3. Clean the tool delicately, without completely removing the factory lubricant.
4. When the lock nut is tightened, it is prohibited to rotate the handle.
5. If the torque wrench has been stored without use for a long time, do not try to immediately set a large force on the scale; first check it in operation at a small torque value.
6. It is prohibited to use pieces of pipe as extensions and to use a torque wrench as an impact tool.
7. It is recommended to install only standard attachments.
8. Throwing the tool on the ground or hitting the torque wrench is prohibited.
9. The products are stored in a dry, clean place, and sent for long-term preservation in a lubricated form.
10. During operation, the spring mechanism weakens, so periodically the keys should be checked independently or sent for calibration.
