A Beginner’s Guide to Using a Click Type Torque Wrench

A click type torque wrench is a specialized tool that allows you to apply the perfect amount of torque to a fastener, ensuring that it is tightened to the optimal level of tension. This is important because overtightening a fastener can cause damage to the threads or the surrounding material, while under-tightening can lead to a failure of the fastened joint.

Here, we will provide a step-by-step guide for using a click type torque wrench, along with some tips for ensuring accuracy and consistency. So let’s get started!

How to use a click type torque wrench

Choosing the Right Click Type Torque Wrench

Choose the best click torque wrench for your needs by following these things-

Measurement system:

Torque wrenches are available in two measurement systems: inch-pound (in-lb) and Newton-meter (Nm). In-lb torque wrenches are commonly used in the United States, while Nm torque wrenches are more widely used in Europe and other parts of the world. So, it is crucial to choose a torque wrench that is compatible with the measurement system used in your region or industry.

Range:

Torque wrenches have a specific range of torque that they can measure. It is important to choose a torque wrench with a range that is appropriate for the fasteners you will be working with. If you try to use a torque wrench outside of its range, it does not provide better performance.

Accuracy:

The accuracy of a torque wrench is expressed as a percentage of the full-scale value. For example, a torque wrench with an accuracy of +/- 4% will provide measurements that are within 4% of the actual torque value. Always choose a torque wrench with a high level of accuracy to ensure that you apply the correct amount of torque to the fastener.

Size and style:

Click-type torque wrenches are available in various sizes and styles, including fixed, reversible, and adjustable heads. So, it is also important to choose a torque wrench appropriate for the size and style of the fasteners you will be working with.

Preparing to Use a Click Type Torque Wrench

Proper preparation is essential for ensuring the accuracy and performance of your click type torque wrench. Here are some steps to take before using your torque wrench:

  • Calibrate your torque wrench: Most torque wrenches have a calibration adjustment feature that allows you to fine-tune the tool to ensure that it provides accurate measurements. Calibration should be performed regularly, according to the manufacturer’s recommendations.
  • Check for damage: Inspect the torque wrench for any visible damage or wear. If you notice any issues, do not use the tool until it has been repaired or replaced.
  • Lubricate the tool: Some torque wrenches require lubrication to ensure smooth operation. Follow the manufacturer’s instructions for lubricating the tool using the recommended lubricant.
  • Follow proper safety precautions: Always wear protective gear, such as safety glasses and gloves, when using a torque wrench. Follow the manufacturer’s instructions and any relevant safety guidelines when using the tool.

Using a Click Type Torque Wrench

There are beam, dial, and click type wrenches available. Click-type torque wrenches, also known as “clicker” or “ratcheting” torque wrenches, are particularly popular because they are easy to use and offer more accuracy.

Using a click type torque wrench is relatively straightforward, but it is essential to follow the manufacturer’s instructions and observe proper safety precautions. Here is a step-by-step guide for using a click-type torque wrench:

  1. Select the appropriate size and style of torque wrench that is suitable for the fastener you will be working with.
  2. Set the click torque wrench to the required torque level according to the manufacturer’s specifications or your desired tension level.
  3. Position the torque wrench on the fastener. The wrench handle is facing away from you, and the head is in contact with the fastener.
  4. Slowly apply pressure to the torque wrench handle, turning the fastener in the desired direction (clockwise or counterclockwise).
  5. As the desired torque value is reached, the torque wrench will emit an audible “click” and may also have a visual indicator (such as a needle on a dial).
  6. Once the “click” is heard, stop applying torque and remove the torque wrench from the fastener.

Common mistakes to avoid when using a torque wrench:

  • Applying too much torque, which can strip the threads or cause damage to the fastener or surrounding material
  • Applying too little torque, which can fail the fastened joint
  • Using a torque wrench that is not calibrated correctly or maintained
  • Failing to follow the manufacturer’s instructions or industry standards for torque values

Tips for ensuring accurate and consistent torque measurement:

  • Use a click torque wrench that is appropriate for the size and style of the fastener
  • Follow the manufacturer’s instructions for calibrating and maintaining the torque wrench
  • Avoid using the torque wrench for purposes other than tightening fasteners (e.g., prying or leverage)
  • Avoid using the torque wrench in extreme temperatures or humid environments
  • Avoid exposing the torque wrench to oil or other corrosive substances

Advanced Techniques for Using a Click Type Torque Wrench

Several advanced techniques can be used to enhance the accuracy and versatility of your click type torque wrench.

Using a torque wrench with extension bars or adapters: Extension bars or adapters can be used to increase the reach of the torque wrench, allowing you to access fasteners in hard-to-reach locations. It is essential to ensure they are compatible with your torque wrench when using these accessories.

Tips for using a torque wrench in tight or awkward spaces:

  • Use a reversible head torque wrench, which allows you to change the direction of the handle to suit your needs
  • Use a flexible head torque wrench, which allows the head to be rotated to any angle
  • Use a torque wrench with a long handle, which provides additional leverage and helps to reduce the risk of hand fatigue

FAQS

What are the benefits of using a click-type torque wrench?

Here are some benefits of using a click-type torque wrench-

  • It provides an audible “click” when the desired torque level is reached, which helps to eliminate the risk of overtightening
  • Allows for precise torque measurement in both clockwise and counterclockwise directions
  • The compact and lightweight design makes it easy to use in tight or awkward spaces
  • Durable construction allows for long-term use with proper maintenance

Do click type torque wrenches require calibration?

Do you know if your click type torque wrench accurately measures the torque you apply to your bolts and nuts? It’s important to regularly calibrate your click type torque wrench to ensure that it is providing accurate measurements. You risk either overtightening or under-tightening your fasteners without proper calibration, which can lead to damage or failure. Don’t take the chance – calibrate your click type torque wrench according to the manufacturer’s recommendations to ensure precise and safe torque measurement every time.

How often should you click a torque wrench?

Are you wondering how often you should “click” your torque wrench before considering the fastener tightened? The answer is simple: just once! The “click” sound that a click type torque wrench makes indicates that the desired torque level has been reached. Any additional clicks could overtighten the fastener, which can cause damage or failure. Always listen for the first “click” and stop tightening once you hear it to ensure that you apply the correct amount of torque to your fasteners.

Why does my torque wrench not click?

If your click type torque wrench is not clicking when you use it, there is something wrong with the tool.

  • One possible reason for this issue is that the torque wrench is not calibrated correctly.
  • If it has been damaged or misused, it may not produce the “click” sound when the desired torque level is reached.
  • Other possible causes of a non-functioning “click” include a malfunctioning mechanism or damaged internal components.

If you are experiencing this issue, it is recommended to have the torque wrench inspected and repaired by a professional.

Conclusion

A click type torque wrench is a reliable and accurate way to apply the correct torque to fasteners. By following the manufacturer’s instructions and observing proper safety precautions, you can ensure that your fastened joints are secure and your equipment is operating at its best. Remember to choose the right size and style of a torque wrench for your needs, calibrate and maintain the tool regularly, and use advanced techniques to enhance its versatility and performance.
