When it was first developed in 1918, no one could have anticipated the widespread application of the torque wrench. However, these days, it has evolved into one of the most widely used instruments in each and every household. First, let’s review some of the fundamentals of using a torque wrench. If you follow these four steps, I have no doubt that you will become an expert user of a torque wrench. Take a look at it:
A torque wrench and its advantages
A instrument known as a torque wrench is utilized for the purpose of applying a predetermined torque to a fastener such as a nut or bolt.
The most common type of this tool is a socket wrench, which has specialized components on the inside. Its original purpose was to prevent workers from overtightening bolts while making adjustments to underground water mains and steam pipes. Fixing the wheel on a vehicle is yet another application, and today we will go over how to do just that.
You might believe that installing spark plugs, working on your yard or garden equipment, or performing any of these other tasks does not require the use of a torque wrench. However, it is a well-known truth that the majority of people who attempt to do their own repairs overtighten virtually everything. Because of this, excessive tightening can result in damaged equipment as well as fractured bolts and stripped threads. Because of this, we absolutely need to have a torque wrench.
If you have a torque wrench and the torque number recommended by the manufacturer, you will be able to solve any problem: When you have achieved the desired torque with a “clicker” torque wrench, an audible click will sound. On the other hand, with a “beam-style” wrench, you simply monitor the scale and stop when you reach the appropriate number.
After familiarizing ourselves with the fundamentals of torque wrenches, we can move on to the following four steps:
1. Purchase a torque
Naturally, the very first thing that you should do is go out and purchase it. However, in order to select the one that is most suitable for you, here are some tips:
- There are four distinct kinds of torque wrenches, and they are called beam, click adjustable, meter gauge, and digital electronic. The manner in which they are viewed and the degree of flexibility they offer are two aspects that set these formats apart from one another.
- Take a beam style torque wrench with you if you are concerned about the simplicity of use as well as the overall cost of the tool.
- Utilize a click adjustable torque wrench if you need precision and the tool will be used on a regular basis.
- Make sure the torque wrench you are using has been calibrated (you can do this at an auto parts store or a supplier that sells brand new ones), or if yours is used, you can return it to the store to have it recalibrated there. In addition to that, don’t neglect to study its framework.
2. Research the torque specifications for your project
This information is typically presented in the form of a recommended amount of foot-pounds. If you are unable to locate this specification within the provided instructions, please search the Internet for it. The next step is to take careful notice of the sequence in which the directions instruct you to tighten the fasteners. (e.g. a star pattern or starting in the middle and alternating between the two sides).
3. Prepare the nuts and bolts
Because a torque wrench will not function as effectively on threads that have been damaged in any way, you need to make sure that all of your nuts and bolts are spotless, dry, and undamaged. In addition, if you are not cautious, you might end up having to take the fasteners apart at some point in the future.
4a. Use the dial torque wrench
To begin, use a wrench or socket to tighten the bolts onto the threads, and continue doing so until the bolts are secure. After that, you can proceed with the next step, which involves the tension wrench.
The second step is to secure your hold on the torque wrench’s plastic handle. It is imperative that you hold the handle in such a manner that it is positioned on the pivot. When aiming for precision, make sure that neither end of the handle is contacting the bar.
The next step is to position the end of the torque wrench in a comfortable position where you can see the beam in its direct line of sight. After that, you will proceed to the next step. Avoid looking at it at an acute angle.
To finish, turn it in a clockwise direction until you can achieve the specified torque. Tighten the remaining fasteners in the recommended direction using the same method as you did with the first set.
4b. Use a click adjustable torque wrench
You can continue to work with the click adjustable torque wrench even though you have been using the manual type up until now. It’s possible that some stages are the same:
To begin, use a spanner or a socket to snugly secure the bolts onto the threads until they are completely secure. The very first stage is unaltered in any way.
Second, you will need to make the necessary adjustments to your torque tester. Then, turn the dial used to regulate it counterclockwise. First, spin the handle until it achieves the torque specification, and then turn the adjustable dial clockwise until it is as tight as possible.
Third, grasp the handle and position it so that the handle is on the left side of the fastener. Place the tip on the fastener. This is referred to as technique, and you are required to observe it.
It is essential that you follow this procedure: turn the handle clockwise until you hear a click, then turn it back the other way until you hear another click. This will ensure that you have applied the correct amount of power.
In the end, move around the project and strengthen the fasteners in the pattern that was recommended for you, and you will have fulfilled your responsibility. When you are finished, you must ensure that the zero setting on the torque tester is restored. This will assist you in lowering the pressure that is being placed on the internal spring, and you will be able to maintain it calibrated without having to return to the store.
Some helpful tips when you are working with the torque wrench
And that concludes the walkthrough for utilizing the torque tester. And here is my gift to you: a few hints that will be useful to you when you are interacting with your torque:
1. Tighten fasteners in two steps – first to half torque, and then to the complete amount of torque.
2. Clean dirty or rusted threads before tightening, However, you should not lubricate them unless specifically instructed to do so by the manufacturer of the apparatus.
3. Never use your torque wrench as a breaker bar –That will cause the tension mechanism to malfunction.
4. Carry it with kid gloves – There is a possibility that a solitary fall could reduce accuracy by as much as thirty percent. If you happen to lose it, you need to have it recalibrated before you use it again (see below for a list of companies that do calibration).
5. Don’t oil the threads before. This has the potential to decrease friction while simultaneously increasing the load on the bolt.
In a nutshell, what I want to talk about today is everything that was mentioned above. You can now go and purchase a torque tester in preparation for the various projects that require tightening. Don’t forget to tell us about your experiences, and don’t be afraid to get in touch with us if you run into any problems.
