Why use a torque wrench ?
There are several reasons why using a mechanical torque wrench is important. First, it helps maintain accurate and consistent tightening tension. This is important to ensure the safety and reliability of equipment and structures. Over-tightening nuts and bolts can damage surrounding components and can also pose a safety hazard if vibration or load increases.
Using a mechanical torque wrench ensures that all nuts and bolts are properly tightened to extend the life of your equipment and structures.
In addition, mechanical torque wrenches automatically stop when the required force is reached, helping to eliminate human error, eliminating the risk of overtightening. This prevents costly damage to equipment and structures, as well as downtime for repairs or replacement.
Finally, mechanical torque wrenches are widely used in industrial applications and quality standards, so using these tools ensures that they meet the required quality standards.
Factory preset or customer adjustable :
Factory pre-set torque equipment are clamping tools that are set to a specific clamping tension at the factory before being shipped to the customer. These tools are often used in applications where precise tightening tension is essential, but operators do not need to change wrench settings frequently.
On the other hand, customer-adjustable equipment allows the operator to adjust the clamping tension according to the needs of the application. These tools are often used in applications where operators need to change the tension frequently, such as to accommodate different sizes of bolts or screws.
Factory preset tools are often considered dedicated to a certain type of tightening or loosening, while customer adjustable equipment is more versatile and can be used in a variety of applications.
However, it is important to note that both types of equipment can be very useful in applications where clamping tension accuracy is important. Factory preset tools offer a simple and reliable solution for operators who do not need to frequently change wrench settings, while customer-adjustable tools offer more flexibility to accommodate different applications.
Two types of torque wrenches: dial or trigger
Torque wrenches are tools that measure the amount of tension applied to a bolt or screw. These wrenches ensure that the bolt or screw is tightened to the correct tension to avoid safety or performance problems.
Dial torque wrenches are wrenches that display the tightening tension in real time on a dial. They are often used in applications where an accurate reading of the tightening tension is important. They are also useful when the wrench head cannot be seen directly, as the dial can be placed in a visible location.
Trigger wrenches are another type of torque wrench that use a trigger mechanism to indicate that the correct tightening tension has been reached. These wrenches are often used in applications where accurate and consistent tightening tension is important, such as in aerospace, automotive and industrial applications.
Trigger wrenches can be set to trigger at a specific tightening tension, and once that tension is reached, the wrench emits a signal, usually a click or vibration, to indicate that the bolt or screw is properly tightened.
Ultimately, the choice between a dial torque wrench and a trigger wrench will depend on the specific application and the user’s preferences. Both types of wrenches are very useful in ensuring that bolts and screws are tightened to the correct tension, which helps to avoid safety and performance issues.
How to select the torque of your torque wrench?
To select the torque of your torque wrench you need to use either the digital display screen or a vernier. A vernier is a scale of graduation that will allow us to select a value manually.
What is the unit used to express its torque?
The units that can be used to express the torque of a torque wrench are Newton-meters (Nm) or meter-kilo (m.kg).
For example, a torque of 20 Nm (which is equivalent to 2 m.kg) represents a force exerted by a mass of 1 Kg which would be at the end of an arm of 1m .
Does a torque wrench need to be calibrated?
Yes this tool must be calibrated and checked before being put on sale because it is certified to meet the standards. Indeed the torque wrench is a fragile tool, so it should not be dropped to prevent it from becoming out of adjustment. If this is the case, it is important to have it recalibrated..
Is there a tool similar to the torque wrench ?
For meticulous fastenings such as for electrical panels, bicycle and automobile linkages.. It is possible to use torque screwdrivers specifically adapted.
They are characterized by their ability to “disengage” i.e. the screwing head blocks but the handle continues to turn in the vacuum once the desired torque is reached.
