Precisely what Torque Wrenches? What precisely Undertake These Undertake?

 

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 an automobile, hopefully you used a torque wrench.

A torque wrench is a wrench built to let you tighten nuts or bolts without over-tightening them, that is prevented in many different ways.

Lets return to the lug nuts. If the lug nuts on your car or truck need to be tightened to 75 foot pounds you need to be sure you have a means of knowing when you've reached 75 foot pounds. Are you just going to utilize a regular wrench and guess?

That's why I said above that "hopefully" you used a torque wrench. A typical torque wrench can have a measure on it that teaches you how much force you're applying. As you tighten the nuts the needle will indicate the amount of force being used which will allow you to apply precisely the right amount.

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

While some kinds of these wrenches just have a measure to share with you how much force you're applying, others have mechanisms that keep you from applying too much force. For instance, some wrenches have a clutch that disengages when the right amount of force is applied so that you cannot tighten the bolt any further.

Now, imagine if you're working together with bolts which are much larger compared to lug nuts that hold your wheels on? What if you want to tighten something to 10,000 feet pounds instead of 100? In these cases there is a different 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 considering that the mid-60's but recent improvements within their design have made them smaller, lighter, and and more easily able to fit into tight spaces. This type is recognized as better than pneumatic wrenches as they are quieter, lighter, and more accurate.
