A torque wrench is a tool used to precisely tighten up nuts and bolts. This is used when the tightening required is to a particular load so that the nuts and bolts do not break or become loose over a period of time. Automotive garages to household use one can see many situations where the toptorquewrench is going to be handy. It is a calibrated tool which works with formula t = f x l. that means the amount of torque purely depends on the length of the wrench and the force you apply on the handle.
The main five things you need to understand about a torque wrench are as given below:
Storing a torque wrench in a place like an automotive garage where it is being put to use on every day, you need not wound back. But if you are going to keep it aside for a longer period of time it needs to be wound back to a minimum level.
Minimum level means not zero. Wounding back to scale setting of zero and keeping it aside also is as damaging as not winding back. In both cases, the spring and other parts inside the wrench might get disoriented which makes the torque wrench weak or not functioning at all.
One Click is more than sufficient as said earlier it is a calibrated tool. The torque required can be set and one click will do the job. If you click it multiple times that may bring in more torque which makes the bolts damaged.
Direction Most torque wrenches are designed for clockwise direction use and if a particular demand comes in where the screw thread is anti-clockwise, read the user manual first of the torque wrench. This is to understand whether the wrench supports this anti-clockwise direction or not. If it doesn’t support and you use it for anti-clockwise it may destroy the wrench completely. Know about marked loading point torque wrenches work on the length of the wrench plus the force applied. If you closely look at the handle there is a point known as marked loading point. Most people tend to ignore at use handle directly. But according to the calibration, if you place your hand on the marked loading point, it will yield the best possible result.Unbolting using torque wrench.
The whole success while unbolting using a torque wrench is not over doing it. If the screw is not completely out with the maximum torque then it is always better to use another tool. If you overdo it while loosening the bolt you can damage the wrench. On using in such a way the accuracy can be disturbed and this can create problems while using it in the future. Also be cautious while using the torque wrench in many other situations like adding a handle extension, and when handling crow foot like situations. Also one need to understand that, there are different types of torque wrenches available in the market for different kind of uses. Some of the common types available are a beam, deflecting beam, slipper, and click. Electronic torque wrenches, hydraulic torque wrenches, and mechanical torque wrenches are also available. The idea is to choose the best one suitable for your use.
