How to Use Snap on Torque Wrench

By Richard S. Clark | Last Updated: February 18, 2022

If you own a movable property such as a car, then you need to know how to use the snap on a wrench. They help in determining the amount of torque to apply when tightening a bolt or a nut. There are some different types of wrenches that can tighten but will not stop at the appropriate time. The snap-on torque comes in handy to rectify the situation. It is, therefore, advisable to learn how to utilize this resource when working on automobiles. Read through this article to understand more about how to use it.

The steps to follow are:

Set up the torque wrench

On the handle of your tool, locate the dial. It is on the side of the wrench. You will notice that it appears more of a pressure gauge of the tire pump. The dial displays the quantity of pressure that the tools required to use. It does so by moving the dial from one side to another. The outcome is the change in the amount of force that the torque wrench will use. Here, you will need to understand how the dial works.

Study the bolt or the nut

Get to understand the details of the item you are to adjust. Put the torque wrench to the desired setting. Luckily, some manufacturers provide a user manual. These documents guide on the manufacturer’s recommended limits on the amount of torque to apply while using a snap. You will also get to know the amount of tension to apply from the user manual.

Do not work on a bolt or a nut if you do not have the correct facts. You may end up damaging your product instead of improving on it!

Adjust the dial

After ascertaining the amount of torque that you require, you can adjust appropriately by moving it in or out, as you desire. Make sure that the torque wrench and the units along the side are in unison. If the two are not in sync, then the outcome of your adjustments will be substandard. Make sure that you are applying a standard measurement to the two components.

In most cases, there are two systems of measurements. They are the metric system and the US system. You will need to decide or settle on the unit to use before placing the wrench on the bolt.

Test the wrench

Before doing the actual work, you may find it fit to try out on a different bolt. It will give you a clear picture of what to expect when you begin working on your automobile. Where possible, you can get a professional to guide you through the process, especially if it is your first time! It is not, however, a difficult task to undertake, as long as you apply the standard units of measurements to the two sets of tools.

Finally, observe the direction of the dial during the test process.

Get the right socket head

Do not snap the torque wrench before you get the correct socket head for the bolt. When you find it, then you can proceed to place it over the bolt. It should then snap either on or off the bolt. If you get into trouble with the socket, then you should consider getting another one.

After snapping the torque wrench into the bolt, begin tightening it by use of smooth and even strokes. When you get to the right amount of tightness, then you will feel the wrench snapping it off. In a real sense, it is the wrench releasing the bolt instead of damaging it!

The task is complete

After undertaking all the above steps, the work will be complete.


Using a snap on a torque wrench is one of the modern methods to tighten bolts and nuts without damaging them. The trick is to use a standard unit of measurement when working on a bolt or a nut. If the dial and the side of the torque wrench are not in unison, then you may find it hard to proceed without destroying the tool. Another thing is to make sure that you are either using the metric system or the US model per session. Using both for the same assignment can bring confusion to the system. It may even end up damaging the bolt, nut, or even the wrench.

Before working on any item, please consult the user manual first.
