Exactly what are Torque Wrenches? Just what Carry out They will Carry out?

 

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 a wrench made to enable you to tighten nuts or bolts without over-tightening them, which will be prevented in many different ways.

Lets go back to the lug nuts hydraulic torque wrenches. If the lug nuts on your car or truck must be tightened to 75 foot pounds you need to make sure you have a means of knowing when you've reached 75-foot pounds. Have you been just going to utilize 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 on it that demonstrates to you simply how much force you're applying. As you tighten the nuts the needle will indicate the total amount of force being used that may permit you to apply the right amount.

Most wrenches of this sort 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 an easier time than if you try it with a 10" wrench, for example.

While some forms of these wrenches only have a measure to tell you simply how much force you're applying, others now have mechanisms that prevent you from applying a lot of force. For example, some wrenches have a clutch that disengages when the proper level of force is applied so you cannot tighten the bolt any further.

Now, what if you're dealing with bolts which can be bigger compared to 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's a different type of wrench, a hydraulic torque wrench, that uses hydraulic power to use the required 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 quicker able to match into tight spaces. This sort is considered much better than pneumatic wrenches since they're quieter, lighter, and more accurate.
