Know More About the Torque Wrench

The wrench is a very practical tool that helps to loosen or tighten the nuts and bolts of any object. They can be used for domestic, mechanical and industrial purposes. There are numerous variations of wrenches that can be found in the market and one of the most widely used models is the torque wrench. This is an exceptional type of wrench that has an indicator to guide the user when to discontinue the tightening process after the right torque has been effectively applied.

What is Torque Wrench?
It's usually an uncomfortable situation to be in if they're talking to you about something and they are using words or terms of which you don't know the meaning, so before we get into talking about torque wrenches, let's first start by looking at what exactly a torque wrench is.

A torque wrench is a wrench which is designed to apply a certain amount of force (known as "torque”) to a nut or bolt. When non-mechanical individuals hear the word "torque" they usually assume "isn't that the same as horsepower?" Torque does, in general, is the force rotating something about an axis (for instance the wheels of your car or truck), but that word can speak of anything in that situation; not only how powerful your car's engine is.

A wrench is a tool that is used for mechanical and electrical purposes to tighten and loosen nuts and bolts. The torque wrench is also a type of wrench that has a special indicator feature that tells the user that he has applied a certain level of torque on the nut or the bolt. This wrench helps you to avoid any kind of extra tightening of the nut or the bolt that may cause damage to it.

A torque wrench can be used where the tightness of bolts and nuts is important. It enables the operator to measure the torque used on the fastener so that it can suit the specifications for a particular use. This allows proper tension and loading of all the parts. A torque wrench assesses torque as a proxy for bolt tension. The process suffers from inaccuracy as a result of inconsistent or uncalibrated friction between the fastener as well as its mating hole. Calibrating bolt tension (indirectly through bolt stretch) is precisely what is desired, but often torque happens to be the only practicable measurement which can be made.

Most manufacturers will definitely have torque specific features listed for specific fasteners. Torque wrenches are employed to tighten fasteners thoroughly without over-tightening and breaking up the fastener. For example, if you're tightening two pipe flanges altogether the pipe flanges should have five bolts and nuts merging them together. A torque wrench will make sure all five bolts and nuts are equally tightened.

Tips for Using a Torque Wrench for the Beginner
It is important to talk about some necessary tips for using a torque wrench for those who are unfamiliar with how to tighten the fastener appropriately. If you have to use a torque wrench for whatever task you are carrying out you will need to be sure that you're using it properly. The torque features to which you are tightening to is likely to be involved with deciding bearing clearances, in this case, the appropriate use of a torque wrench is not only important but necessary.

So listed below are the basic tips to be familiar with:

  1. When you are grabbing the torque wrench, ensure that you grab far down the shaft and not up by the dial. Grabbing far down gives you more control and leverage over the wrench and fastener.
  2. When you're checking out your project, tighten the bolts or nuts down in a sequence that will enforce load or pressure equally across the item. Do not put it to use in a pure clockwise or counter-clockwise direction. Whatever is been tightened have to move down evenly or your readings may be off drastically.
  3. When working on a number of bolts or nuts, stiffen them until they are tight, after which you can go back over them for the final tightening and reading. This is stated to make sure that you are applying an even load on the surface you're working on. This is useful general information that has also become a necessity when making use of a torque wrench on a surface that needs specific torque pressure.
  4. When you use your torque wrench always make sure the bolts or nuts move freely along the threads you're tightening against. I like to make use of an assembly lube specially designed for this application. Provided the fastener has resistance in its moves along the threads your torque readings will need to take that resistance into account in form of metered torque even though the readings might in any other case indicate that the fastener is perfectly torque, it won't be.            

Different Types of Torque Wrench

Apart from knowing how to use these tools, it is also important to learn about the different models available. Torque wrenches have been in existence for nearly a century. There are different types in use today. They range from the simplest, the beam type, to the advanced, programmable electronic torque/angle wrench. Determined by the application, other torque tools are available today. There are different types of wrench devices that have certain features and are designed for varied projects.

1. The Beam Torque Wrench
The beam type is the first of them that is made of a long lever arm specifically between the handle and the head. Moreover, it is made of a material that comes with the ability to bend flexibly each time some torque is applied to it. There exists a small bar with an indicator that has been connected to the back of the head of the wrench. This indicator is placed parallel to the lever arm; therefore, the smaller bar does not come under stress. There is a calibrated scale that has been attached to the handle. Every time the main lever is twisted the scale moves and when the shown level of torque is applied the lever stops. Among these tools, this is the most affordable and easy ones to use.

2. Deflecting Beam Torque Wrench
The other well-known wrench tool is the deflecting beam which is also known as the dual-signal deflecting beam. This torque wrench is effective in the technique of applying torque to a deflecting beam rather than a coil spring. This will help the wrench to function effectively and the user gets correct and consistent readings. The good thing about the deflecting beam torque wrench is the fact that the user gets total control over the usage of this type of torque wrench with warnings that cannot just be seen but also heard.

3. Click Type
There are more torque wrench tools like the "click type" that can be pre-programmed to get the preferred torque. This tool can make a sound when the clutch slips on reaching the desired torque. The user decides the amount of torque that should be attained. This type of torque wrench provides you with the right precision that needs to be achieved. There are a huge number of specifications that one can choose from and they make sure you get the maximum benefits. This type of torque wrench is needed when it comes to taking preventive measures to stop the scooping of the heads of the screws. This wrench is been used in industrial and mechanical setups on a large basis.

4. No-hub Torque Wrench
The last but not the least, the torque wrench tool is the no-hub wrench that is a different kind of wrench for soil pipes. They can be used by plumbers for tightening up clamps. They have the series of the clutch along with the ratchet and the shaft of the no-hub wrench which consist of a folding handle that can be used by the operator for loosening the clamps.
