How to define Torque Wrenches? Everything that Achieve Some people Achieve?

 

If you've ever loosened lug nuts on car to take the wheels off or tightened them after putting the wheels on, you've probably used a torque wrench. Well, allow me to rephrase; if you've ever put the lug nuts back on a vehicle, hopefully you used a torque wrench.

A torque wrench is just a wrench built to let you tighten nuts or bolts without over-tightening them, which can be prevented in a number of ways.

Lets go back to the lug nuts. If the lug nuts on your car must be tightened to 75 foot pounds you will need to be sure you have a way of knowing when you've reached 75 foot pounds. Are you just going to use a regular wrench and guess?

That's why I said above that "hopefully" you used a torque wrench. A regular torque wrench can have a measure onto it that demonstrates to you how much force you're applying. As you tighten the nuts the needle will point to the amount of force used that'll allow you to apply the right amount.

Most wrenches of this kind are fairly long to allow sufficient leverage to generate enough force. If you're tightening your lug nuts with a 16" wrench you're going to own a much easier time than if you try it with a 10" wrench, for example.

Although some kinds of these wrenches only have a measure to inform you how much force you're applying, others now have mechanisms that prevent you from applying a lot of force hydraulic torque wrenches. As an example, some wrenches have a clutch that disengages when the correct level of force is applied so that you cannot tighten the bolt any further.

Now, imagine if you're dealing with bolts which can be much bigger than the lug nuts that hold your wheels on? What if you want to tighten something to 10,000 feet pounds as opposed to 100? In these cases there is another type of wrench, a hydraulic torque wrench, that uses hydraulic power to apply the mandatory force to the bolts. Hydraulic torque wrenches have been around since the mid-60's but recent improvements within their design have made them smaller, lighter, and and easier able to match into tight spaces. This sort is recognized as better than pneumatic wrenches since they are quieter, lighter, and more accurate.
