How Does Torque Wrench Works?
Usually, it puts you in an uncomfortable situation if you are talking to someone and they’re using terms or words of which you do not even know the meaning. So just before we start diving into learning what torque wrenches are, let us first start this article by knowing what a torque wrench exactly is.
As a matter of fact, torque wrench is another type of wrench that is designed in such a way that it can apply specific amount of force or also known as torque to a bolt or nut. People often think of the engine’s horsepower when average individuals have heard of the word torque. Well, torque does refer to a force rotating such as the wheels of a car but that term can also refer to almost anything in that case and not only the power of your car’s engine.
Another common example for this involves lug nuts that hold the wheels on an automobile. These lug nuts have a specific amount of torque in which they must be tightened. Say for example that there’s lacking in the amount of force used, there’s a chance that it could come loose while driving and can result to unstable wheel or worse, your wheel may come off. If they are too tight on the other hand, you are running the risk of something cracking that can cause some problems on the wheels. For this reason, making use of a torque wrench should be considered if ever these nuts have to be applied with specific torque or amount of force.
For the most basic type of this wrench, it has a small gauge showing how much force you’re applying. And in case for lug nuts, cars usually need 80 pounds of force, what you have to do is put the wrench on and then tighten it until it shows that you are applying 80 pounds of torque and you are good.
The 10 Best Resources For Wrenches
There are many types of torque wrenches and with the most basic being what mentioned above. Normally, it is using a needle in order to indicate the amount of force applied. Some also have mechanisms that are preventing you from over-tightening, which might have clutch that will disengage when you reach that certain amount of force. For this, it is preventing additional force to be applied.
Lessons Learned from Years with Wrenches
Again, there are electronic wrenches that have a digital display than an analog gauge. Moreover, there are hydraulic torque wrenches that are available in the market as well which is capable of applying significant amount of force by using hydraulics. In most instances, you’ll see this being used in bigger pieces of machinery where basic wrenches would not work.
