A torque wrench  is an essential device for individuals and companies involved in auto repair, construction, manufacturing, or DIY projects at home. In its basic form, the primary application of a torque wrench is to apply a manageable amount of force or torque to a bolt or nut for two key reasons: to prevent over-tightening, which can break threads or parts, and under-tightening, which can lead to loosening and detachment. For any auto technician, mechanical engineer DIY car enthusiast, improving the quality and reliability of work done by using of Torque Wrench properly is very important. Please keep reading to know more about torque wrenches, their types and their working.

1. What is a Torque Wrench?

A torque wrench is a type of wrench that is used to produce a predetermined amount of torque in order to fasten or undo nuts and bolts. It is often used in operations that require precise torque, such as fixing car tire nuts, erecting machinery, or working on engines. A torque wrench is a device majorly used to apply and accurately measure force to turn nuts and bolts to a specific tightness because over-torquing may cause damage, while under-torquing may result in the disjoining of the joined parts within a short span.
Torque wrenches are adjustable to produce the necessary torque for the task, ensuring correct direction and quality assurance. That is why it is extremely useful for maintaining the integrity and performance of components that have been joined together. Among ONEVAN, our 1/2 1200N·m Brushless Cordless Impact Wrench is highly regarded for its versatility, ranging from construction work to automobile repair.

Types of Torque Wrenches

Torque wrenches come in various types, each designed for specific applications and user preferences:

1. Digital Torque Wrenches: These tools also include an electronic display that displays torque value in order to assist in adjusting torque.
2. Dial Torque Wrenches: However, these wrenches are fitted with a dial gauge, which enables an individual to see just how much torque is being applied.
3. Preset Torque Wrenches: Even these are set to a particular torque setting and the user cannot be allowed to make any changes.
4. Automatic Torque Wrenches: Automatic torque wrenches are designed to automatically stop applying torque once a predetermined torque value is reached. These wrenches typically have a built-in mechanism that disengages or slips when the desired torque is achieved, preventing over-tightening. They may also feature audible or visual indicators to signal when the torque limit has been reached.
5. Non-digital Torque Wrenches:  Non-digital torque wrenches refer to torque wrenches that do not have electronic displays or sensors. These wrenches rely on mechanical mechanisms, such as springs or click mechanisms, to indicate when the desired torque has been achieved. They are manually set to the desired torque value using a scale or markings on the wrench and provide reliable torque control without the need for digital components.

2. Why Use a Torque Wrench?

These torque settings play a crucial role in achieving the recommended clamping force for fasteners, ensuring safety and performance. A torque wrench helps here by applying the correct torque; either under-tightening or over-tightening can be damaging to the bolt. If fasteners are tightened below the specified torque level, the joint may not have sufficient clamping force and may be unsafe for use, with certain failure of the joint and overall assembly as a result.
Conversely, applying excessive torque can damage the threads on the component, strip, bend, or break parts, which can be expensive and dangerous. When properly done, each part of the component is properly tightened, and you minimize the chances of mechanical failure and stress on the individual parts, hence increasing their life spans and improving the overall system efficiency. There are endless reasons to use the torque wrench. 

Applications of Torque Wrenches

Torque wrenches are widely used in various fields:

1. Automotive Repair: Torque wrenches allow for the proper tightening of wheel lug nuts and various engine components to the correct torque.
2. Construction: Any structural work requires the protection of structures and large machines/equipment where safety is of the essence. The 1/2 2800N·m Brushless Cordless Impact Wrench by ONEVAN is a versatile tool suited for heavy-duty construction tasks.
3. Manufacturing: Collecting parts in products that need to be fastened with control to work to the best of their capabilities.

Consequences of Improper Using a Torque Wrench

Improper use of a torque wrench can have serious consequences:

1. Mechanical Failures: Excessive tightening often results in damaged bolts or even thread damage.
2. Safety Hazards: Unscrewing screws are potentially dangerous the in case of automobiles because wheels might come loose. Without any doubt, safety comes up with any cordless impact wrench
3. Increased Maintenance Costs: Since improper fastening requires frequent repairs, then the operational cost would be high.

3. How to Use a Torque Wrench?

Using a torque wrench involves knowledge of how it works and must be applied according to certain procedures depending on its kind. Torque wrenches are measuring instruments employed to secure a definite amount of force with the fasteners without over or under-tightening the fasteners. Here are specific tutorials for different types with a focus on how to set, calibrate, and operate, as well as how to make the devices accurate for various uses.

How to Use a Digital Torque Wrench

Step-by-step Guide to Using a Digital Torque Wrench

1. Set the Desired Torque Value: Switch on the wrench and turn the required torque setting with the buttons on the tool.
2. Attach the Socket: Importantly, ensure that the appropriate socket is securely attached to fit the fastener.
3. Position the Wrench: Put the wrench over the fastener in a perpendicular manner to the pointed end of the fastener.
4. Apply Pressure Gradually: Apply torque gradually by turning the handle until the desired torque is reached.
5. Listen for Beeps or Watch for Lights: Most digital wrenches have a buzzer/alarm and or an LED or flashing light to signify when the tool has reached the desired torque.

Important Considerations

1. Ensure that your battery is charged before use.
2. Familiarize yourself with how to interpret the display readings.

How to Use a Dial Torque Wrench

Step-by-step Guide to Using a Dial Torque Wrench

1. Zero Out the Dial: At the start, set the dial to zero before pulling the starter.
2. Attach Your Socket: Choose and screw the right size of the socket onto the driver.
3. Position and Apply Force: Put the wrench on the fastener and twist the wrench continuously till its dial gets to the desired number.
4. Stop When Reaching Set Value: The continued application of force beyond the value of torque that you wish to achieve is discouraged and should be ceased as soon as you get your desired torque value.

Important Considerations

1. Make sure you read at eye level for accurate measurement.
2. Avoid sudden jerks; apply steady Pressure.

How to Use a Preset Torque Wrench

Step-by-step Guide to Using a Preset Torque Wrench
