The definition of Torque Wrenches? What exactly Complete Many people Complete?

 

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, i'd like 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 designed to allow you to 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 or truck must be tightened to 75 foot pounds you will need to ensure you have a means of knowing when you've reached 75 foot pounds. Have you been just going to use a regular wrench and guess?

That's why I said above that "hopefully" you used a torque wrench. A standard torque wrench will have a gauge on it that shows you just how much force you are applying hydraulic torque wrenches. As you tighten the nuts the needle will indicate the total amount of force getting used that will enable you to apply exactly the right amount.

Most wrenches of this type are fairly long allowing 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 in the event that you test it with a 10" wrench, for example.

While some forms of these wrenches only have a gauge to share with you just how much force you're applying, others now have mechanisms that prevent you from applying a lot of force. Like, some wrenches have a clutch that disengages when the correct amount of force is applied so that you cannot tighten the bolt any further.

Now, what if you're dealing with bolts which can be much larger compared to the lug nuts that hold your wheels on? What if you need to tighten something to 10,000 feet pounds as opposed to 100? In these cases there's 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 with us since the mid-60's but recent improvements within their design have made them smaller, lighter, and and easier able to fit into tight spaces. This type is considered much better than pneumatic wrenches since they're quieter, lighter, and more accurate.
