How Does a Click Torque Wrench Work?

If you’re in the market for a torque wrench, you may have come across one that is referred to as a “click” torque wrench. But what is a click torque wrench, and how does it vary from other kinds of torque wrenches? Please keep reading to learn more about click torque wrenches and how they work.

How does a click torque wrench work?

A click torque wrench can apply preset adjustable torque to move fasteners without damage. When the preset amount of torque has been reached, the wrench will click, indicating that it is time to stop tightening the fastener.

Click torque wrenches work by utilizing a tension spring inside the wrench body. As the fastener is tightened, the tension in the spring increases until it reaches the point where the spring can release its energy. When this happens, an internal pawl engages with teeth on the drive shaft, causing an audible “click” sound. Further turning of the wrench handle will not result in additional torquing force being applied to the fastener.

Using a click torque wrench is relatively simple. First, you’ll need to set the desired amount of torque by turning the adjustment knob until it lines up with the corresponding hash mark on the tool’s body. Next, simply attach the wrench to the fastener and begin tightening it until you hear a click. Once you hear the click, you’ll know that you’ve applied enough torque and can stop tightening.

Follow these things to work a click torque wrench properly

Performing a click torque wrench is critical to ensuring the accuracy of your torque readings. Here are four things to follow:

  • First, make sure the wrench is calibrated correctly. This can be done by checking the manufacturer’s specifications or sending the wrench to a professional calibration service.
  • Second, attach the wrench to the working surface. The wrench must be securely mounted so that it does not move during use.
  • Third, select the appropriate torque setting. Consult the manufacturer’s specifications or an expert if you are unsure which setting to use.
  • Finally, apply torque to the working surface and then release it when the desired reading is achieved. It is important to keep a steady hand while using the wrench to ensure accuracy.

These steps will help ensure you get accurate readings from your click torque wrench.

When should we use a click torque wrench?

Torque plays a vital role in many mechanical applications, from cars to bicycles. If a nut or bolt is too loose, it can come undone, leading to dangerous consequences. On the other hand, if it is too tight, it can strip the threads or damage the component. As a result, it is essential to use a click torque wrench to ensure that nuts and bolts are tightened to the correct specification.

A click torque wrench can be handy in a few different situations. For example, when working with delicate components made from soft materials such as aluminum, it is crucial to avoid overtightening, which can cause damage.

In addition, click torque wrenches can be used in situations where there is limited space to apply torque by hand, such as when working with recessed bolts. Finally, they can be handy for ensuring that nuts and bolts are tightened evenly, preventing uneven stress that could lead to failure.

FAQS

Will a torque wrench keep tightening after the click?

A torque wrench is usually used when it is important not to overtighten or under-tighten a fastener. Most torque wrenches have a knob that can be turned to set the desired level of torque and a mechanism that will click when the desired torque has been reached. Once the click is heard, the operator can stop applying force to the wrench.

In most cases, the wrench will not continue tightening after the click. However, there are some instances where the clicking mechanism may become damaged or dislodged, causing the wrench to keep turning after the click is heard. If this occurs, it is essential to stop using the wrench immediately and have it repaired by a qualified professional.

Is a click torque wrench better than a digital one?

Different types of torque wrenches are available, so it can be challenging to select which is suitable for your needs. If you’re trying to decide between a click torque wrench and a digital torque wrench, it’s vital to know the pros and cons of each type of wrench.

Click torque wrenches are typically more affordable than digital torque wrenches, and they’re also easier to use. However, they’re not as accurate as digital torque wrenches and can be challenging to read in low-light conditions.

Digital torque wrenches, on the other hand, are more expensive but offer greater accuracy. They are also more durable than click torque wrenches, making them a good choice for professional mechanics. Ultimately, the best torque wrench for you will depend on your budget and your needs.

How many times should you click a torque wrench?

When using a click torque wrench, it is crucial to follow the manufacturer’s instructions carefully. In general, you should click the wrench once for every unit of measurement that is indicated on the wrench.

For example, if the torque wrench is set to “5 Nm,” you would click it five times. However, it is always best to consult the manufacturer’s instructions before using a torque wrench to ensure that you are using it correctly.

How accurate are click torque wrenches?

Click torque wrenches are designed to be accurate and are often used when precision is required. A few factors can affect the accuracy of a click torque wrench, including the quality of the tool itself and the user’s technique. In general, however, these wrenches are quite accurate and can be relied upon to provide consistent results.

Conclusion

If you need a reliable way to apply a particular amount of force to a fastener, then a click-type torque wrench may be just what you’re looking for. These wrenches work great, are easy to use, and provide an accurate reading every time, making them essential for anyone who works with fasteners regularly.
