What Exactly Is The Use Of Torque Wrench?
It is often uncomfortable to be in a situation when talking to someone and they are talking about something using terms or words that you don’t have any idea about. 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.
Basically, torque wrench is a type of wrench that’s designed to be able to apply specific amount of force or otherwise referred to as torque to a bolt or nut. Whenever non-mechanic individuals heard of torque, they immediately jump to a conclusion that it is the engine’s horsepower. It is true that torque is referring to a rotating force like the wheels of a car but that term can refer to nearly anything in that case and not just the power of engine in your car.
Yet another example of 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. In the event that too little amount of force is used, they may come loose while you are driving which can lead 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.
When you are making use the basic type of this wrench, you’ll see a small gauge showing how much force you’re applying. And let’s use the lug nuts of your car in this case which typically needs 80 pounds of force, what you must 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.
How I Became An Expert on Wrenches
There are many types of torque wrenches and with the most basic being what mentioned above. Normally, to be able to indicate the amount of force applied, it is using a needle. There are some that have mechanisms which will prevent you from over-tightening through the use of a clutch that disengage automatically when you reach that certain amount of force. For this, it is preventing additional force to be applied.
A Brief History of Tools
Then again, there are electronic wrenches which come with 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.
