A torque driver is a screwdriver with components that ensure tightening to a specified torque. They enable any consumer to deliver the correct torque with confidence regardless of task and operator skill level, making them a must-have in any [tool kit](https://my.rs-online.com/web/c/hand-tools/tool-kits-tool-storage/tool-kits/).

## **What Is a Torque Driver?**

Unlike the [standard screwdrivers](https://my.rs-online.com/web/content/discovery/ideas-and-advice/screwdrivers-guide) you can get in a traditional [screwdriver set](https://my.rs-online.com/web/c/hand-tools/screwdrivers-hex-torx-keys/screwdriver-sets/), torque screwdrivers are able to detect or control how much force is applied to a screw. This is crucial as inadequate force may cause the screw to become loose, and the mount won't be securely attached. Conversely, applying too much may harm the substrate or the screw, increasing the likelihood that the whole assembly will collapse under stress either right now or in the future.

To ensure both precision and durability, torque drivers are typically made from steel with ergonomic multi-component handles. As a result, you can expect the best adjustable and preset torque screwdrivers to be sturdy and durable even with extended use and for heavy-duty applications.

## **How Do They Work?**

Torque screwdrivers are designed to apply a specific amount of force, measured in inch pounds, to a screw. By setting the desired torque, the screwdriver prevents over-tightening, ensuring components are securely fastened without damage.

### **How to Use a Torque Screwdriver**

Using a torque screwdriver is straightforward, but there are a few key steps to ensure proper and safe operation:

1. **Adjust the Torque Setting**
    - Ensure the torque value is set to the specifications required for the task.
    - Adjust the torque setting on the screwdriver to the appropriate value, whether it is a preset, adjustable, or digital model.
    - Double-check the torque setting to avoid over-tightening or under-tightening the fasteners.
2. **Choose and Fit the Appropriate Screwdriver Tip**
    - Select the appropriate screwdriver bit or tip that matches the screw head size and type.
    - Firmly insert the tip into the screw head, making sure it is properly seated.
3. **Apply Torque Slowly and Steadily**
    - Grip the torque screwdriver handle and apply torque slowly and steadily.
    - For hand tools, use your body weight and leverage to apply the necessary force.
    - For powered tools, let the motor do the work and avoid excessive force.
4. **Monitor the Torque Indicator**
    - Watch for the torque screwdriver's indication that the desired torque has been reached, such as a "click" or "slip" on a hand tool or a digital readout.
    - Stop applying force once the torque indication is triggered to prevent over-tightening.
5. **Repeat as Needed**
    - Move on to the next screw, repeating the process to ensure consistent torque is applied across all fasteners.

## **How to Choose a Torque Screwdriver**

Choosing the right torque screwdriver can be crucial for ensuring precise and reliable fastening while preventing damage to screws and materials. Here are some key considerations and potential pitfalls to avoid:

- **Torque Range**: Select a torque screwdriver with a torque range that matches the requirements of your application. Using a screwdriver with too high a torque setting can overtighten screws and damage materials, while too low a setting may result in loose connections.
- **Drive Type and Size**: Ensure the screwdriver’s drive type and size are compatible with the screws you will be using. Common drive types include Phillips, slotted, Torx, and hex.
- **Accuracy and Calibration**: Choose a torque screwdriver with the appropriate accuracy for your needs. For critical applications, consider a screwdriver with higher accuracy and regular calibration to ensure consistent torque application.
- **Ergonomic Design**: Select a screwdriver with an ergonomic handle that provides a comfortable grip and good control during use. This is especially important for extended use or high-torque applications.
- **Features**: Consider whether you need an adjustable torque screwdriver or a preset one with a fixed torque setting. Adjustable screwdrivers offer flexibility for various applications, while preset screwdrivers are ideal for repetitive tasks with specific torque requirements.

**Pitfalls to Avoid**:

- **Overtightening**: Avoid overtightening screws, as this can damage materials and lead to joint failure.
- **Using the Wrong Drive Type**: Using an incorrect drive type can damage screw heads and make it difficult to achieve proper torque.
- **Neglecting Calibration**: Regular calibration is essential to maintain the accuracy of your torque screwdriver, especially for critical applications.
- **Ignoring Ergonomics**: Using an uncomfortable screwdriver can lead to fatigue and reduced control, increasing the risk of errors.

## **Types of Torque Drivers**

By their method of propulsion, the many varieties of torque screwdrivers may be divided into three major groups: pneumatic, electric, and manual. The ideal one for your use will rely on your intended production rate, needed torque output and precision, documentation requirements and the size of the screw you will be dealing with. Here are some of the types of torque screwdrivers we carry at RS Malaysia:

- **T-bar Torque Drivers**: T-bar torque drivers are a type of hand torque screwdriver that feature a T-shaped handle. This design provides more leverage and allows the user to apply higher torque values compared to standard straight-handle screwdrivers. The T-bar shape gives the user more control and stability when tightening screws that require higher torque.
- **Electric Torque Drivers**: Electric torque drivers are powered by an electric motor, providing faster operation and more precise torque control compared to manual hand tools. They are well-suited for high-volume or delicate assemblies where consistent torque is critical. Electric torque drivers can be integrated with automated systems and some models are designed to prevent electrostatic discharge, making them safe for electronics work.
- **Preset Torque Screwdrivers**: Preset torque screwdrivers are hand tools that are factory-calibrated to a specific torque value. They use an internal mechanism that "clicks" or "slips" once the preset torque is reached, preventing over-tightening. Preset screwdrivers offer reliable, repeatable torque application but require a separate screwdriver for different torque settings.
- **VDE Torque Drivers**: Verband Deutscher Elektrotechniker (VDE) torque drivers are a specialised type designed for working on live electrical equipment. They feature an insulated handle and other safety features to protect the user from electric shock hazards. VDE torque drivers allow technicians to properly tighten live electrical connections safely.
- **Digital Torque Screwdrivers**: Digital torque screwdrivers use electronic sensors and displays to provide a precise, digital readout of the applied torque. This allows the user to accurately monitor and control the torque being applied, ensuring consistent and reliable results. Digital models often include features like data logging and wireless connectivity.
- **Adjustable Torque Limiting Screwdrivers**: Adjustable torque limiting screwdrivers allow the user to set the desired torque value, then automatically disengage or "slip" once that torque is reached. This prevents over-tightening and damage to delicate components.

The ideal torque screwdriver type will depend on the specific requirements of the application, such as required torque range, production speed, screw size, and the work environment. Many businesses utilise a combination of different torque screwdriver types to meet their diverse needs.

## **What Are Torque Drivers Used For?**

Torque screwdrivers ensure precise tightening of screws, preventing damage from overtightening or loosening due to under-tightening. This is crucial in manufacturing and maintenance across various industries where consistent screw tension is vital for product quality, safety, and efficiency.
