A torque wrench is a really useful piece of equipment as it helps eliminate the over-tightening of bolts which may cause them to break or end up with a piece of damaged equipment. If you are a DIYer, you definitely need a torque wrench to assist you in installing spark plugs on your car or work on your lawn and garden equipment, among other tightening works. To prevent costly fixes, use a torque wrench. The tool utilizes a rotational force to fasten a bolt or nut with little effort and more accuracy than standard wrenches. In this article, we will guide you on how to use the torque wrench effectively.

How To Use a Torque Wrench

A torque wrench is a handy tool that is used to apply torque as a proxy to bolts, nuts, or screws. It tightens a bolt to a definite pressure. Different types of torque wrenches are found on the market for different purposes. Some of them are Hydraulic Torque Wrenches, Electronic Torque Wrenches, Beam, and many more. Using this tool can save your valuable time and minimize your efforts in automotive maintenance. Below I have listed ten easy steps that can help use a torque wrench properly.

Step one: Buy a torque wrench.

Ensure that the torque wrench that you purchase is calibrated. Buy this straight from an auto-parts store or supplier. If you decide to go for a used wrench, ensure you take it for calibration from an auto-part. Pick a torque wrench that is suitable for your task. Some of the examples include: click adjustable, beam, digital electronic, and dial gauge. A torque wrench would cost around 40$-100$ depending on models and sizes.

Step two: Research the torque wrench features for the project at hand

This will usually be noted in the number of foot-pounds that are suggested. For instance, it may show 30 or 100 ft-pound is suggested for a particular bolt. This data can also be found online.

Step three: Make sure that you’re utilizing dry and unmanaged nuts and bolts

If the nuts or bolts are damaged, the torque wrench won’t function well. In addition, this might cause issues removing when removing the fasteners in the future. Also, wet or lubricated blots reduce torque.

Step four: Stiffen the bolts onto the threads with a wrench or socket until they are snug

Read the manual and set your wrench to one-half of the required torque. Never overtighten the nuts because that may break the warped rotors. After you have tightened the bolts, you can then follow up with the torque wrench.

Step five: Hold the plastic handle of the torque wrench firmly

Then, hold the torque wrench’s plastic handle firmly so that it is centered on the pivot. For accuracy, avoid neither end of the handle touching the bar. Try to avoid using an extension on the wrench’s handle.

Step six: Put the wrench in a position that you can read the beam

Place the end of the torque wrench and be in a comfortable position where you can read the beam straight on. Don’t view it from an angle.

Step seven: Tighten it clockwise until you reach the suggested torque

After tightening clockwise, stiffen the other fasteners in the suggested direction with the same technique. It is essential to check the wrench’s level and manual carefully because some torque wrenches indicate in the anti-clockwise direction.

Step eight: Adjust the torque wrench to tighten the bolts

Tighten the bolts or nuts onto the threads with a wrench until they are a snug fit. Then adjust the torque wrench as needed. Loosen the adjustable dial. Turn the handle until it attains the torque specification, and then stiffen the adjustable dial. Then, hold onto the handle and put the tip on the fastener with the handle on the left side.

Step nine: Turn it clockwise until you hear a click

Repeat on the same handle until you hear another click to make sure that you’ve attained the suggested force. Then, move around the project tightening the fasteners in the suggested pattern.

Step ten: Reset the torque wrench to zero when you finish

A torque wrench is a tool that is used on a regular basis. So you need to wind it down to the bottom scale setting. Reset the torque wrench to zero when you are done, as this will greatly lower the pressure on the internal spring and assist in keeping it calibrated.

Conclusion

I hope you have already learned how to Use a Torque Wrench perfectly. As seen from above, a torque wrench is very easy to use as long as you know what steps to take. Learn how to use it today and ensure you don’t over-tighten your nuts or bolts, which may lead to damage to the equipment.
