Don’t buy a Torque Wrench before you read this!

There are several factors to consider before purchasing a torque wrench, such as accuracy, size, type (manual or digital), and intended use. It’s also important to consider the brand and reputation of the manufacturer, as well as any warranty or after-sales support offered. By taking the time to carefully evaluate these factors, you can make an informed decision and choose a torque wrench that best meets your needs and expectations.

Brand

One of the most important is the brand. It’s important to choose a reputable brand that uses high-grade materials and precise manufacturing processes to produce durable torque wrenches that are resistant to damage. 

Type 

Factors to consider include the type of torque wrench (manual, digital, or dial), as well as any additional features that may be important for your specific application.

Costing

When it comes to purchasing a torque wrench, it’s important to remember that you get what you pay for. While it may be tempting to opt for a cheaper model with fewer features, it’s important to consider the long-term value of investing in a high-quality wrench. 

While it may come with a higher price tag, the added features and durability of a top-of-the-line wrench will likely pay off in the long run. Rather than compromising on features for the sake of cost, it’s often worth it to invest in a feature-rich and reliable torque wrench.

Size 

Torque wrenches come in four different sizes: 1/4 inch square drive, 3/8 inch square drive, 1/2 inch square drive, and 3/4 inch square drive. 

The first three sizes are commonly used in the automotive and light automation industries, while the 3/4 inch square drive torque wrenches are better suited for larger applications such as aircraft, tractors, large cargo ships, windmills, and more. 

It’s important to choose the right size torque wrench for your specific needs to ensure accurate and efficient fastening.

Accuracy and Calibration

Accuracy is a crucial factor to consider when selecting a torque wrench. A tolerance of plus or minus 4% is generally considered acceptable, although higher precision is always preferred. Many high-quality torque wrenches, such as those made by KANON in Japan, offer a tolerance of plus or minus 3% thanks to their advanced manufacturing processes and precision engineering. It’s also important to ensure that your torque wrench is well calibrated, as this will ensure clear scale visibility and reliable readings. By paying attention to these details, you can be confident in the accuracy and performance of your torque wrench
