Most people are familiar with the "standard" torque tool - which looks like a ratchet drive socket wrench. Other torque wrenches include:

Preset torque tools: Also known as torque drivers. They are small and usually gripped with the palm of your hand. The torque is set to a specific amount. They are popular with cyclists due to their portability and light weight.

Deflecting beam torque tool: Available in many ranges from light engineering to industrial. The long beam extends from the head, where the socket is mounted, to the scale at the grip. This beam's deflection, either left or right, shows the torque. The socket is a popular and common tool used in many industries. It's difficult to use if you don't have enough space.

There are some differences between the micrometer torque tools that we are all familiar with and those that are not.

There are different sizes of drive along with different torque wrenches. Tools designed for automotive applications are commonly equipped with a 1/2" drive. Other common drives include 1/4", 3/8", and 3/4".

It is simple to use the popular mechanical torque wrench, but it can have settings that slip. This is prevented by a locking collar, also known as a sliplock.

A longer handle allows you to maintain control when working with high torque settings. Ratchet heads allow you to work with larger tools without having to worry about space.

You're less likely than ever to drop the torque wrench, especially on cold days.

Some digital models shut down automatically if unattended. This conserves battery life. Some models have charge indicators. Manufacturers like to add bells, whistles, and other features to lure you in. You should consider whether the added features are worth it or if they're just gimmicks.

Our recommendations are based on the click-type torque wrench or its digital equivalent. The following characteristics and rules can be applied to all types of torque wrenches.

The accuracy of the torque wrench can be expressed as:

Full Scale (FS) or Indicated Value

It can be confusing.

It is possible that a torque wrench with a quote of +/-4% on the Full Scale may not be as accurate at other points (typically lower torque settings) along the scale. The overall accuracy of the torque wrench is +/-4%.

Anywhere on the scale, a tool that gives +/-4% for any Indicated value is not more than 4% inaccurate. This tool is more accurate than a full scale.

Manufacturers don't always make this distinction clear. This will depend on how precise your work is. Check with the manufacturer if it is a concern.

It is also important to note that the accuracy of click-type torque tools is not stated over their entire range. Commonly, 20% to 100% are quoted. It's because this type of mechanism has difficulty maintaining control and accuracy at the lower end.

If, for example you have a wrench that has a range of 25 to 250 foot lbs, it might not reach its accuracy stated until it reaches 45 foot lbs (20% range). It may be necessary to select a smaller range if you require accuracy in a lower setting. If you need accuracy at a lower setting, it may be necessary to choose a wrench with a smaller range.

Dial-type torque wrenches, on the other hand, can provide accuracy between 0% and 100%. They are, however, much more expensive.

The dial looks like an analog click wrench, but it is only there to guide you and not to set torque limits.

Pros:
Durable. It can be extremely accurate.

Cons:
Bulky. Bulky. Dial wrenches are difficult to use because they require a high degree of skill from the operator. The majority of dial wrenches do not have an audible alarm, nor will they break or turn over. You need to watch the dial and respond accordingly.

Click wrenches are similar in appearance. They have a slip mechanism built in that releases the pressure when a set torque is achieved.

Pros:
Simple to use. Even with repeated pressure, the nut will not become over-tightened. It guarantees repeatable accuracy, regardless of user skill level.

Cons:
The complexity of the mechanisms makes them expensive.

They are the latest development and are quite common. The LCD display shows torque readings. As the desired torque is neared, "traffic light" LEDs or audible alerts will change.

Pros:
Four decimal places accuracy is possible. Prices are now competitive. Some of them can store data to be compared later and for record keeping.

Cons:
They are not mechanically limited, so they depend on the user's skill. Electronic components are a concern. There are no advantages to mechanical alternatives.

Similar to click-wrenches, but have a hinged portion - usually near a socket head – that "breaks" once the torque required is reached.

Pros:
Easy to use. Value for money and good durability. When used correctly, accuracy is possible.

Cons:
If you continue to press after the break, it will cause over-tightening. Some people find 'break' unpleasant.

The torque is measured on the imperial scale in foot pounds (ft. lbs. The metric system of Newton meters is also available. It can be measured in inch-pounds (in), which is less common. lbs.) or kilograms per centimeter (kg. cm. ).

The mechanical torque wrench has one or both of these scales.

Not all models can be digitalized. Do not assume that this is the case.

This is the most common type. When the torque required is reached, the user will hear a click and feel it through the grip.

Pros:
The combination of performance, durability and ease of use is excellent. When used correctly, it is accurate.

Cons:
They can overtighten if pressure is applied too quickly. It is best to apply steady pressure and stop immediately after the first click. Users often think that they must release the pressure and click an additional time "just to be sure." This is not correct.
