7 Factors To Consider Before Buying A Torque Wrench


When it comes to torque wrenches, choosing the right one for your needs can be overwhelming. With various types, features, and brands available in the market, it’s important to understand the key factors to consider before making a purchase. In this guide, we will walk you through everything you need to know to make an informed decision when buying a torque wrench.

1. Types of Torque Wrenches

There are several types of torque wrenches to choose from, each designed for specific applications. The most common types include click torque wrenches, beam torque wrenches, dial torque wrenches, and electronic torque wrenches. Understanding their features and limitations will help you select the right one for your tasks.

2. Torque Range

Determining the torque range you require is crucial. It is essential to choose a torque wrench that can handle the minimum and maximum torque values needed for your applications. Consider the specific requirements of your projects to ensure the torque wrench you choose is suitable.

3. Size

There are four different sizes of square head range, all of which correspond to different torque range and functions.

  • The 1/4 in. drive: Suitable for small nuts and bolts like on garden equipment, bicycles, and motorcycles. They produce between 4 to 21 ft-lb of torque.
  • The 3/8 in. drive: Suitable for a majority of automobiles such as passenger vehicles, light trucks, and cars. They produce 15 to 75 ft-lb of torque. It is the most versatile size and covers a wide range of functions.
  • 1/2 in. drive: Covers larger nuts and bolts like in engine mounts and suspensions.
  • 3/4 in. drive: Essential for special applications like in large cargo aircraft and tractor trailers.

4. Accuracy and Calibration

Accuracy is a critical aspect of torque wrenches. Look for wrenches that have high accuracy ratings, typically expressed as a percentage of the applied torque. Additionally, consider the calibration process. Some torque wrenches require periodic calibration to maintain their accuracy, while others offer self-calibration features.

5. Durability and Quality

Investing in a durable and high-quality torque wrench is essential for long-term use. Look for wrenches made from robust materials such as steel or alloy, as they tend to be more reliable and withstand heavy-duty applications. Read customer reviews and consider reputable brands to ensure you are purchasing a reliable product.

6. Ease of Use

Consider the ergonomics and ease of use of the torque wrench. Look for features such as comfortable handles, clearly marked scales, and user-friendly adjustment mechanisms. A user-friendly torque wrench will make your work more efficient and reduce the risk of errors.

7. Price and Warranty

Compare prices from different brands to find a torque wrench that fits your budget without compromising quality. Additionally, check the warranty offered by the manufacturer. A longer warranty period indicates the manufacturer’s confidence in their product’s durability and performance.


Buying a torque wrench requires careful consideration of several factors, including the type, torque range, accuracy, durability, ease of use, price, and warranty. By understanding these key aspects, you can confidently select the right torque wrench for your needs. Remember to prioritize quality and reliability to ensure your torque wrench serves you well in various applications.
