Torque Wrenches: Their Different Types and How to Use them

Torque wrenches are considered tools rather than measuring instruments. The measure of torque that torque wrenches provide is always visible to control the amount of torque applied in fastening and assembly tasks. Torque is the force applied at a perpendicular distance of its line of application from the point of fulcrum. Or, you can say that it is the amount of force needed to rotate the object with the pivot point as the axis for rotation. There are many industries and technologies in which torque wrenches like Norbar torque wrench ½ are used, such:

  • Safety engineering
  • Offshore industry.
  • Material testing
  • Screw and assembly technology.
  • Aviation industry
  • Marine drive technology.
  • Automotive industry
  • Medical meas. Technology.
  • Automation technology.
  • Viscometry. 

Torque wrenches make sure that the fasteners are not damaged by over-tightening, and they also do not come apart from under-tightening. This indicates that applying the correct torque measure is very important for equipment safety, assembly, and performance.

Measurement of Torque

Using hand torque measuring tools makes it easy to measure the torque in the production process, known explicitly as assembly tools for nuts and screws. These tools can be divided into two types, known as the dial indicating and clicker tools.

Dial-Indicating Torque Wrenches

These TWO are designed for the appropriate utility and size of any torque cost, without the need for ancillary calibration or putting gadget. They usually have bi-directional tightening. The instant torque cost is displayed continuously on analog or virtual display; the consumer appears on the show simultaneously as working the device and forestalls tightening when the desired torque fee is completed.

These torque wrenches are an instrument; they provide excellent results and usually have decent repeatability and mid reproductivity like the Norbar torque wrench ½. Due to such reasons, dial torque wrenches are considered the most accurate ones. One drawback of dial indicators is that they may be more comprehensive than other wrenches, making them hard to use in closed spaces. These tools are commonly used in the automotive, aerospace, and defense industry. 

Click Torque Wrenches

From the name, we can tell that the click torque wrenches will make a clicking sound when the suitable amount of torque is achieved. Click wrenches consist of a lever with springs that can be adjusted by twisting the handle towards the right side. When the needed torque level is reached, the level will detach, making a clicking sound. Usually, these wrenches are ratchets and can be used for tightening and loosening purposes and are highly flexible, making the degree of repeatability and reproducibility lower like a Norbar Torque wrench 3/8. 

Slipper Torque Wrenches

A slipper torque wrench is a type that the user cannot adjust. The wrench does not consist of an indicator or set scale. A slipper wrench is also known as a production wrench. It is set up against a calibration device and then used for a specific application; in such cases, constant modifications of nominal torque value are not needed. This is considered an excellent torque wrench as it does not allow unauthorized alterations and eliminates over-tightening. 

Beam Torque Wrenches

These merchandises are typically inexpensive and smooth to apply. They characteristic a scale, and once the right torque stage has been reached, it stops at the suitable variety.

The critical beam has a handle on it used to appoint force. When in use, the beam stays in the region, and the dimensions indicate the extent of torque. This equipment can be used for tightening or loosening.

Electronic Torque Wrenches

Electronic torque wrenches are digital torque wrenches and work based on a sensor. They do not consist of any moving components. Electronic torque wrenches consist of a digital display from which you can measure how much torque is being applied. These wrenches can save the readings with a small chip that has been installed with a memory stick. You can access that data of readings through a computer.

Hydraulic Torque Wrenches

Hydraulic torque wrenches are most commonly used in industrial setups with a wide range of uses in Hydraulics. They are designed to reach the required torque level in Hydraulics effectively.

How To Use Torque Wrenches

It’s critical to apply tools that have been nicely calibrated. If it’s been calibrated, it needs to be validated with a sticky label at the tool.

They frequently have a lock that wishes to be disengaged earlier than the deal can be circled. Once the lock has been taken off, rotate the cope to line up the range with the centerline at the barrel. Then positioned the lock directly to keep away from any danger of adjusting the setting when using it.

When using a click-on torque wrench, use one hand to preserve the pivot in the vicinity with the other hand on the handle. Then turn the device it makes a sound you can hear. As quickly as that occurs, stop turning, as one click is all that’s wanted in any other case; the fastener can be overtightened.

Once the tool, like a Norbar torque wrench 1/2 300nm, is no longer needed, position the size back in its lowest setting to prevent impacting its accuracy for future measurements.
