How Does a Torque Wrench Work?

You use a standard wrench to tighten the lug nuts or bolts on your wheel. How’s the experience? It requires a lot of effort, and it is exhausting to use. 

No wonder why a torque wrench is increasing its importance in today’s market. If it is your first time hearing a torque wrench, there is nothing to be afraid of because you are in the right place. 

What is a Torque Wrench? 

A torque wrench is simply a tool designed to tighten bolts and nuts. Unlike the standard wrench, this modern and top-grade instrument allows fasteners to be tightened according to their proper tension without over-tightening or under-tightening. The first torque wrench was designed by Conrad Bahr in 1918. 

Why Should You Use a Torque Wrench? 

Many people believe investing in a torque wrench is a waste of money and time, especially when they have a standard wrench. But why do most DIYers and other skilled professionals switch to this instrument? Here are some reasons a torque wrench is a perfect addition to your collection: 

–Used for a wide range of tasks

 A torque wrench is developed for construction, automotive, home repairs, and maintenance, to name a few, making it a versatile and sought-after instrument to invest in. 

–It avoids damages and unnecessary costs

It is common to under or over-tighten nuts and bolts with a standard wrench. But with a torque wrench, you can prevent any damage caused by under or over-tightening and other unexpected expenses. 

–It increases your safety

Not tightening lug nuts can cause a wheel to fall off, leading to accidents and injuries. Do not wait for the time when you get injured because of that. It is time to upgrade to this professional-grade, cutting-edge, and long-lasting tool. 

How it Works

To apply enough amount of torque to fasteners, these tools should be calibrated. The amount of torque depends on the wrench length and handle. 

Calibrating a torque wrench is a procedure developed to check the instrument’s accuracy. Like other tools, the accuracy and consistency of a torque wrench decrease over time, and calibration can come into play. To calibrate your torque wrench, leave it to an expert for a better and safer result with precision. 

A torque wrench also consists of a built-in mechanical indicator that connects to a calibrated scale and helps you know if the desired torque is reached. It is available with a display screen that is easy to read. If you find something confusing and difficult, do not be afraid to contact the manufacturer of the wrench. 

Popular Types of Torque Wrenches

Torque wrenches come in different shapes and sizes. As a beginner, you may find the variety of choices overwhelming. But knowing each of the types of wrenches may help you make the right buying decision. 

Electronic Torque Wrenches – Digital and Automatic

An electronic torque wrench is famous for a reason. Also referred to as a digital wrench, it works from an electric-powered sensor that senses how much force you apply. It is available with a small chip that saves readings. You can also access it on a computer. But since it is digital, it may cause you a big fortune.

Beam Torque Wrench – Budget-Friendly

When you cannot afford an electronic torque wrench, a beam is an inexpensive and high-quality alternative. It is easy to use and ideal for those who are less tech-savvy. It features a scale and stops when it reaches your preferred level of torque. It comes with a handle that is developed to employ force. Although it is competitively priced, a beam is flexible and can be used for loosening and tightening, too.

Have you been searching for one of the most accurate wrenches? Do not look further than a dial torque wrench. 

If you have spent hundreds of dollars on the damages caused by over or under-tightening, a dial torque wrench is a good investment you can boast to your close friends, relatives, and colleagues. 

However, they are wider than other types of torque wrenches and are harder to use. But that does not mean it is not a quality tool for your automotive repair job. 

Commonly used in the automotive industry, a dial torque wrench is also used in defense and aerospace.
