What exactly Torque Wrenches? Whatever Can Many Can?

 

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 car, hopefully you used a torque wrench.

A torque wrench is really a wrench made to let you tighten nuts or bolts without over-tightening them, that is prevented in a variety of ways.

Lets get back to the lug nuts. If the lug nuts on your car need to be tightened to 75 foot pounds you'll need to be sure you have a way of knowing when you've reached 75 foot pounds. Have you been just going to employ a regular wrench and guess?

That's why I said above that "hopefully" you used a torque wrench. A regular torque wrench will have a gauge onto it that demonstrates to you just how much force you are applying. As you tighten the nuts the needle will point to the quantity of force being used which will permit you to apply exactly 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 own a much simpler time than in the event that you check it out with a 10" wrench, for example.

Although some kinds of these wrenches only have a gauge to tell you just how much force you're applying, others already have mechanisms that keep you from applying a lot of force hydraulic torque wrenches. As an example, some wrenches have a clutch that disengages when the right number of force is applied so that you cannot tighten the bolt any further.

Now, imagine if you're working together with bolts that are much larger compared to lug nuts that hold your wheels on? What if you need to tighten something to 10,000 feet pounds instead of 100? In these cases there is another kind of wrench, a hydraulic torque wrench, that uses hydraulic power to utilize the necessary force to the bolts. Hydraulic torque wrenches have existed considering that the mid-60's but recent improvements inside their design have made them smaller, lighter, and and quicker able to suit into tight spaces. This type is recognized as better than pneumatic wrenches since they're quieter, lighter, and more accurate.
