Exactly what Torque Wrenches? Precisely what Accomplish That they Accomplish?

 

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, let me 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 built to let you tighten nuts or bolts without over-tightening them, which is prevented in many different ways.

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

That's why I said above that "hopefully" you used a torque wrench. A standard torque wrench could have a measure about it that shows you how much force you're applying. As you tighten the nuts the needle will point to the quantity of force being used that will permit you to apply exactly the right amount.

Most wrenches of this type 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 have a much easier time than if you test it with a 10" wrench, for example hydraulic torque wrenches.

While some types of these wrenches only have a measure to share with you how much force you're applying, others have mechanisms that stop you from applying a lot of force. For example, some wrenches have a clutch that disengages when the right amount of force is applied so you cannot tighten the bolt any further.

Now, what if you're dealing with bolts which are bigger compared to lug nuts that hold your wheels on? What if you want to tighten something to 10,000 feet pounds rather than 100? In these cases there is another type of wrench, a hydraulic torque wrench, that uses hydraulic power to utilize the necessary force to the bolts. Hydraulic torque wrenches have been around 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 considered better than pneumatic wrenches since they're quieter, lighter, and more accurate.
