There are many people out there that have heard of a torque wrench, but are still not clear about exactly what a torque wrench is. If I may take a minute to explain, I will explain the simple mechanics of these hand tools for those that are interested.
The torque wrench is a wrench with an elongated handle to give the user control over a specific amount of force, or torque to apply on a particular nut or bolt. The wrench works by setting it to a specific torque amount by adjusting the handle, then turning the wrench until it feels like the wrench slips or “breaks”. This is what the torque wrench was designed for, so that when the pressure becomes too great, the mechanism inside the wrench will absorb all of the force leaving the nut in tact.
Overview Of The Torque Wrench
A torque wrench is not like other hand tools where you just pick up and use without thinking about it. It is a precise instrument that allows you to apply a specified amount of force, or torque to tighten or loosen a nut or bolt. The torque wrench is very much like other socket wrenches, except that usually the handle is elongated to maximize the force applied.
To use the torque wrench, fit the appropriate socket size to the nut. Place the socket over the nut and slowly apply pressure in the direction to either tighten or loosen the nut or bolt. You should be able to clearly see the measurement readings on any quality torque wrench. In the cases of people using a torque wrench for tightening and loosening bolts on cars, which is quite often, it’s a good idea to look up any nut or bolt in the manual for the manufacturer’s suggestion of the amount of torque to apply. You will know if it is tight enough when the mechanism inside the handle releases the force and it feels like the wrench has slipped or the nut has broken.
A torque wrench is a precision instrument and needs the proper care, unlike a saber saw or pair of slip joint pliers. It’s a good Idea to start out with a torque wrench that’s made by a reputable company, for example, I’ve noticed that Neiko Tools makes a one that’s worth taking a look at. If you buy a brand that you’re unsure of, there’s a higher possibility of the wrench breaking or falling out of alignment sooner than later.
If you use your torque wrench and it doesn’t seem like the bolt is tightening up enough, it would be a good idea to visit a calibration shop to get it tested. Try not to remove bolts with the torque wrench, the clockwise/counterclockwise switch is for using it on either clockwise or counterclockwise threaded bolts. Remember to keep your torque wrench in a place where it’s not going to get banged around. This may also cause an inaccurate reading.
Precision Tightening With A Torque Wrench
Cars today aren’t built like they were forty years ago, with parts being made from cheaper and cheaper materials for the purpose being more economical to the manufacturer. This can cost you, the car owner some thousands of dollars down the road though. For example, when tightening the flywheel bolts on most newer cars, if not properly tightened with a torque wrench, you will crack the crank shaft, which will result in a rear main fuel leak. This usually occurs when an unaware individual attempts to tighten the flywheel bolts with an impact wrench.
This is why finding a good torque wrench is key for maintaining the integrity of your engine parts these days. A torque wrench gives you a precise amount of control so you can apply a specified amount of torque (force being applied in the twisting motion) to bolts preventing in parts damage and ultimately, engine failure. There are many manufacturers, but I feel that Neiko Tools makes a good torque wrench that to has held up very well so far. Whichever brand you choose, it’s always a good Idea to make sure when deciding on the best torque wrench for you, to make sure it’s made by a reputable company. Getting a wrong measurement could result in disaster.
