Are you using a torque wrench to fasten a bolt? Are you wondering How Does a Torque Wrench Work? A torque wrench works as a great specialty tool used in construction tasks and auto repair. Once calibrated, a torque wrench will help you determine rotational force or torque certainly. The torque or rotational force is required to determine how much effort is needed to fasten a bolt or nut. This way, you will able to fasten a bolt with less effort and more accurately than standard wrenches. You may not consider the use of a torque wrench when tightening a bolt. But, studies show that most amateur mechanics tend to overtighten just about everything.
Overtightening reduces the functionality of equipment and leads to damaged bolts and stripped threads.

You can extend the lifespan of your equipment and prevent bolts and threads from being broken or stripped. There is a variety of torque wrenches available for a range of mechanical tasks. There is this “clicker” torque wrench that will let you know you have reached the set torque with an audible click.
How Does a Torque Wrench Work?
Torque wrenches work based on the reading of the torque indicator. Therefore, you will know when to stop twisting the bolt. Some torque wrenches come with a dial to set the required torque, but the indicator doesn’t stop using force automatically when the desired torque is reached.
In order for you to stop with those wrenches, there will be a visual signal such as an audible beep or a digital reading or click. Some torque wrenches, however, are difficult to work within tight places were reading an indicator or gauge may not be possible at all.
From the simplest to the most sophisticated, you can see torque wrenches of many kinds. Listed below are the main types of torque wrench:
Beam-type Torque Wrenches
Torque means a twisting force. The wrench head comes with a pointer beam. Since the wrench is twisted, the beam remains in place. There is a scale that indicates the amount of torque, twist, being applied.
For an accurate torque analysis, you need to keep the handle unlocked against the sides of the wrench. The handle should remain afloat when applied. The point is the handle, which “floats” should be kept locked against the sides of the wrench.
It is a much simpler form of the beam-type. The dial indicator torque wrench comes with a dial attached to the case of the wrench. This dial attached indicates the amount of twisting the wrench handle is sustaining.
The torque wrench comes with a spring-loaded lever, which you can adjust to achieve the desired torque reading. All you have to do to achieve your desired torque reading is twist the handle.
Once you achieved the amount of twist you needed, the spring-loaded lever cuts loose, producing a clicking sound.
Torque Sticks (or Torque Limiters)
Torque sticks are small torsion bars that you need to wedge between an air wrench or hand air wrench and a socket. Each torsion bar comes with its twisting setting. When used, the torsion bar will bounce-back the socket.
This will ensure that the torsion bar doesn’t bounce back when tightened any further. The important thing you need to remember is the use of an extension bar. It will alter the torque reading once used on a torque wrench.
The use of different sizes’ extension will cause additional twisting. A 1-inch, 3-inch, or 6-inch extension can be duly noted.
The use of extension will result in a torque reading greater than the actual amount of torque.
If you have a torque wrench to handle your tightening your bolts, then you will be able to increase their durability. Use a torque wrench to determine whether you exceeded the tightening limit. Make sure you have a torque wrench when working with bolts and screws.
