Torque wrenches are essential tools in Australia for tightening fastenings with precision. They allow users to apply a pre-set torque, preventing under-tightening or over-tightening. This is crucial in automotive repairs and construction, ensuring safety and performance while prolonging the life of components.

## **Types of Torque Wrench**

Torque wrenches are available in different variations for a number of applications. Here’s an overview of some of the different types of torque wrenches available:

- **Breaking Torque** **Wrench (or break-over torque** **wrench):** features a pivot point or hinge which ˈbreaks overˈ when the pre-set torque is reached. This allows the handle to move or rotate indicating that the required torque has been applied.
- **Slipping Torque** **Wrench:** Slipping Torque Wrenches disengage or slip once the pre-set torque is reached, preventing further torque application.
- **Click Torque** **Wrench:** Click Torque Wrenches use a mechanical mechanism that produces an audible or tactile click when the pre-set torque is reached
- **Dial Torque** **Wrench**: Dial Torque Wrenches utilise a dial or gauge with a calibrated scale and rotating needle to display the applied torque and indicate the torque value applied.
- **Digital Torque** **Wrench:** [Digital](https://uk.rs-online.com/web/c/hand-tools/spanners-sockets-wrenches/torque-wrenches/?applied-dimensions=4290255874) Torque Wrenches often feature a digital display to provide accurate torque readings. Torque settings can be adjusted and additional features like audible or visual alerts may display when the required torque has been applied
- **Smart Torque** **Wrench:** Smart Torque Wrenches incorporate wireless connectivity such as Bluetooth or WiFi to connect to mobile devices or a computer network via an app or software

## **How does a torque wrench work?**

A torque wrench is a precision tool designed to apply a specific amount of rotational force, or torque, to a fastener. This ensures that fasteners are tightened to the correct specification, preventing damage from over-tightening or loosening due to under-tightening.

Torque wrenches typically have a mechanism that allows the user to set a desired torque value. When the applied torque reaches this pre-set value, the wrench signals the user through a click, a break-over action, or a digital display. This indicates that the fastener has been tightened to the correct torque.

## **How Do You Calibrate a Torque Wrench?**

Calibration ensures that your torque wrench is applying the correct amount of torque. Here's a general procedure for calibrating a torque wrench:

- **Secure the Torque** **Wrench:** Securely mount the torque wrench in a vice or clamp, ensuring the handle is free to move.
- **Set the Desired Torque:** Set the desired torque value on the wrench's scale or digital display.
- **Apply a Known Torque Load:** Apply a known torque load to the wrench using a torque tester or calibration equipment.
- **Compare the Readings:** Compare the reading on the torque wrench to the known torque load applied.
- **Adjust if Necessary:** If the readings do not match, adjust the torque wrench's calibration mechanism according to the manufacturer's instructions.
- **Repeat at Different Torque Levels:** Repeat the calibration process at different torque levels within the wrench's range to ensure accuracy across the entire scale.
- **Verify Accuracy:** After calibration, verify the accuracy of the torque wrench using a torque tester or calibration equipment.
- **Recalibrate Regularly:** Recalibrate your torque wrench regularly, especially if it is used frequently or subjected to harsh conditions. The frequency of recalibration depends on the type of wrench and its usage.

## **Benefits of Using a Torque Wrench**

Torque wrenches offer several advantages in various applications where precise fastener tightening is essential:

- **Prevents Over-tightening:** Over-tightening fasteners can lead to stripped threads, damaged components, and even safety hazards. A torque wrench allows you to apply the correct amount of torque, preventing over-tightening and ensuring the integrity of the assembly.
- **Prevents Under-tightening:** Under-tightening fasteners can cause them to loosen over time, leading to vibrations, leaks, or even complete failure of the assembly. A torque wrench ensures that fasteners are tightened to the correct specification, preventing loosening and maintaining the integrity of the connection.
- **Ensures Accuracy and Safety:** Torque wrenches provide accurate and consistent torque application, enhancing the safety and reliability of critical assemblies. This is particularly important in industries like automotive, aerospace, and manufacturing, where precise tightening is crucial for safety and performance.
- **Extends Equipment Life and Improves Performance:** By preventing damage from over-tightening and ensuring proper clamping force, torque wrenches can help extend the lifespan of equipment and improve its overall performance. This reduces maintenance costs and downtime associated with fastener failures.
- **Complies with Manufacturer Specifications:** Many manufacturers specify torque values for fasteners in their equipment. Using a torque wrench ensures compliance with these specifications, maintaining warranty validity and ensuring optimal performance.
- **Reduces Maintenance Costs:** Proper torque control helps prevent premature wear and tear on fasteners and components, reducing the need for frequent maintenance and replacements. This can lead to significant cost savings over time.

## **How to Choose the Right Torque Wrench**

Selecting the appropriate torque wrench depends on several factors, including the required torque range, application, accuracy needs, and budget.

- **Determine the Required Torque Range and Type:** Identify the range of torque values you'll be working with and the type of wrench best suited for your application. Torque wrenches are designed for specific torque ranges, so choose one that covers the values you need.
- **Consider Accuracy and Calibration:** Accuracy is crucial for ensuring proper fastener tightening. Look for torque wrenches with high accuracy ratings and consider those with calibration certifications for critical applications.
- **Check Drive Size and Durability:** Choose a torque wrench with a drive size that matches your sockets and attachments. Small torque wrenches can be used in more compact setups. Also, consider the wrench's overall build quality and durability, especially if it will be used frequently or in demanding environments.
- **Evaluate Comfort, Grip, and Ease of Use:** A comfortable grip and ergonomic design are important for reducing hand fatigue and ensuring precise control. Look for features like a cushioned handle and a clear, easy-to-read scale or display.
- **Budget Wisely:** Torque wrenches can range in price from budget-friendly to high-end professional models. Determine your budget and choose a torque wrench that offers the best value for your needs. Consider factors like accuracy, features, and durability when making your decision.

## **Industrial Applications for Torque Wrenches**

Torque wrenches are essential tools in various industries where precise fastener tightening is crucial for safety, performance, and reliability. Here are some key industrial applications for torque wrenches:
