If you work with bolts or nuts, you know that getting the right amount of torque is essential for a job well done. Traditional torque wrenches can be tricky, especially if you're working in a tight space or must apply precise force. That's where digital torque wrenches come in. These innovative tools provide precision and accuracy, making it easy to achieve the perfect torque every time. In this article, we'll explore what digital torque wrenches are, how to use them, and the benefits they offer.  

What is a Digital Torque Wrench?   

A digital torque wrench is designed to apply a specific amount of force or torque to a bolt or nut. Unlike traditional torque wrenches, which rely on a user to interpret and read a gauge or dial, digital torque wrenches provide a digital readout of the applied force on an LCD. The ergonomic design and wide torque range make them easy to use and suitable for a wide range of applications.  

Types of Digital Torque Wrench   

There are several types of digital torque wrenches, each with its own unique features and benefits. Some of the most common types include:  

  • Click-Type Digital Torque Wrench 

    This type of wrench emits an audible "click" when the target torque is reached, making it easy to know when to stop applying force.  
  • Dial-Type Digital Torque Wrench 

    This type of wrench uses a dial to display the applied force, making it easy to read and interpret.  
  • Beam-Type Digital Torque Wrench 

    This type of wrench uses a beam to display the applied force, making it easy to see the amount of torque applied.  

How to Use a Digital Torque Wrench   

Using a digital torque wrench is easy, but following the manufacturer's instructions carefully is essential to ensure accurate results. Here's a step-by-step guide on how to utilize a digital torque wrench  

1. Read the Manufacturer's Instructions Carefully  

Before using your digital torque wrench, make sure to read the manufacturer's instructions carefully. It will help you understand how to use the tool and ensure accurate results.  

2. Set the Torque Range  

Once you've read the instructions, set the torque range to the appropriate level for your job. Most digital torque wrenches have a range of between 10 and 1000 Newton meters (Nm).  

3. Attach the Appropriate Socket  

Next, attach the appropriate socket to the wrench. Make sure the socket is the right size and type for the bolt or nut you're working with.  

4. Apply Force  

Apply force to the bolt or nut until the wrench emits an audible "click" (in the case of a click-type wrench) or the LCD display shows that the target torque has been reached. Be careful not to overtighten the bolt or nut, which can cause damage.  

5. Repeat  

If you need to apply torque to multiple bolts or nuts, repeat the above steps for each one.  

Benefits of a Digital Torque Wrench   

There are several benefits to using a digital torque wrench, including:  

  1. Digital torque wrenches provide precise and accurate readings, which can help prevent damage to bolts, nuts, and other components.   
  2. Digital torque wrenches are easy to use, even in tight spaces, and the digital display makes it effortless to read the applied force.  
  3. Most digital torque wrenches have a wide torque range, making them suitable for various applications.  
  4. Digital torque wrenches are designed to be comfortable to hold and use, reducing the risk of hand and wrist fatigue.  


Digital torque wrenches are an innovative tool that provides precision, accuracy, and ease of use. By following the manufacturer's instructions carefully, you can ensure accurate results and prevent damage to bolts, nuts, and other components; whether an experienced mechanic or a DIY enthusiast, a digital torque wrench is valuable in your toolbox.
