Torque Wrench And Its Different Types?

What Is a Torque Wrench?


The greatest tools for the job when it comes to ensuring the integrity of the connections are torque wrenches. The device gives different fasteners, such as bolts and nuts, precise pressure and torque to produce the proper amount of tension while minimizing the possibility of overtightening.

Torque wrenches fall into two primary groups. Two types of people apply torque: first, those who apply a fixed quantity, and second, those who assist in determining the torque being applied to a fastener.

Torque wrenches come in a variety of sizes and capacities and are specifically made to perform certain industrial tasks. Some varieties of torque wrenches are as follows:





The most basic kind of wrench is the beam torque wrench. Between its head and the handle is a lever arm. When the tool is being used for fastening, the torque exerted is shown by the lever arm stretching against the gauge. The wrench’s arm and indicator lie parallel to one another when no pressure is applied. Similar to a weighing scale, the analog scale moves when pressure is applied, and the needle pointer provides a reading. In general, a beam wrench weighs more than other kinds of torque wrenches. In comparison to other torque wrenches, it is also the most affordable, the most reliable, and easiest to use. But the precision of beam wrenches is not infinite.

Key features of beam torque wrenches

  • A long handle with a lever arm and a perpendicular beam comprise a beam torque wrench.
  • When torque is applied, the beam deflects, providing a visible signal of the applied torque.
  • Renowned for precision, especially with proper calibration, due to the clear indication provided by beam deflection.
  • Simple to read and comprehend, making it user-friendly.


A click wrench requires manual reading and has a restricted laser-cut scale. Despite being composed of sturdy metal, it features a self-defense system to prevent overstretching and eventual breakage. The clutch will slide when the necessary amount of torque is reached, which is something you can preset. Because they are so inexpensive and so adaptable, click wrenches are a favorite among small-scale car repair.  But reading from these wrenches takes longer than reading from digital wrenches. Because of this, using these wrenches in commercial garages with large workloads is not recommended.

Precise Torque Adjustment: Click wrenches, with their ability to make perfect torque adjustments at will, are essential for fastening operations to ensure that the tightening the right level is achieved and nothing too loosen or tightened is done.
Clear Feedback Mechanism: The monitored torque is set as its upper limitation when one level of click wrench is tightened enough; as handle tension releases, it emits the clicking sound, which is used as command to stop tightening and boost user’s confidence.
Durable Construction: Manufactured from the tough components, they are more conscious of precise torque readings as period than the click wrenches that are made of softer materials. Hence, this makes the click wrenches very qualitative in terms of efficiency.




Digital torque wrenches, aka electronic digital torque wrenches, highly advanced electronic tools that are specifically calibrated to ensure the utmost in torque balance. This type of accuracy is achieved by e-wrenches that are aided by electronic components, while conventional torque wrenches depend on purely mechanical systems. As a rule, they have an electronic display section that displays its readings in many measurement units quickly, which update as the wrench operates.

Key features of electronic torque wrenches

Digital Display: The torque signal can be electronically obvious with the help of an LCD or LED display on which a current value is displayed with a reference to the needed value.
Programmed Settings: The standard option of the electronic torque wrenches comes with pre-set for limiting the torque as well as other factors like units of measurement which ease the application of special needs like special ones or even the ones accessible by people.
Data Logging: Some particular electronic torque wrench types have a data logging function that allows the torque levels to be recorded and stored to later be documented, analyzed and used for further quality control.




They are in the business of this generation and this aircraft and the space industry that needs the best connections to achieve a lot of tension. A stationary hydraulic cylinder is coupled to a movable wrench drive head ratchet. Engage the flywheel and rotate the crankshaft of the cylinder down through the pawls until the extended cylinder is over the pepper’s teeth. A hydraulic torque wrench unlike the rest specific application of force through the head itself associated with lubrication. It is designed specifically to apply force to the lubricated fastening. A precise prerequisite is essential in instances where the repair engagement would exert excessive force or pressure on fragile vehicle parts such as engine blocks.

Key features of hydraulic torque wrenches

High Torque Output: Hydraulic torque wrenches supply strong torque so that they are a nice choice for industrial applications having higher efficiency.
Precise Torque Control: This enables tighter fastener control through torque accuracy, as well as pinpoint accuracy in tightening fasteners to specifications.
Uniform Torque Distribution: These types of wrenches use hydraulic power and distribute the applied torque uniformly among various nuts and bolts, hence significantly lowering the chances of damage while enhancing the overall efficiency of the work at hand.




A mechatronic torque wrench combines the best aspects of electronic technology, such as error proofreading, with the characteristics of click-type wrenches. The quality of your connections is much improved by the tool’s capacity to troubleshoot errors while you’re working. The indication of readings can be either mechanical or digital, based on the user’s choice. Because these wrenches include a focus controller feature, you have more control over the joints that need to be joined. Furthermore, because these wrenches are small, they may reach joints that are not accessible with a regular wrench.


Key features of mechatronic torque wrenches

  • Mechatronic torque wrenches blend mechanical and electrical components for accurate torque control.
  • They enable continuous torque monitoring with digital screens or indicator lights, assuring correct tightening.
  • With data logging and programmable torque settings, users can customize torque levels and capture information for quality assurance.
