subject: What You Should Know Before Buying Torque Wrenches [print this page] With torque wrenches it is easy to loosen or tighten bolts or nuts on different objects correctly. They are normally used for industrial and home uses. However, unlike the other brands in the market, this one has various that can bring more effectiveness to the user. Starting with the indicator that shows when one should stop tightening, one cannot go wrong with this tool. Since it is a specialized tool, one should learn how to use it properly before applying it for any job.
For a beginner, here are some basic points you have to consider before using the tool. First, when grabbing it, you should go further down the shaft and not at the dial. This is because the lower you grab, the more control you will have over the fastener and the whole toll.
When using it for your projects, you should tighten the nuts in a sequence. This should not be either clockwise or anticlockwise as this will not apply sufficient load on the object. Uneven pressure can have a negative effect on your torque readings.
If you are working on a series of bolts, you should first make sure that all of them are tightened snugly at first. You should then go over them for a final round of tightening and reading. This step is essential for general projects to ensure you are applying the right load in all areas. However, it becomes a must if the surface you are working on requires a specific torque pressure.
When fixing the nuts and bolts, it is good to make sure that they move freely on the threads. This will ensure that the readings you take when tightening are accurate. If there is resistance, the readings will not be accurate, which can result in insufficient pressure when tightening.
Once you know how to use the tool effectively, it is good to learn about the different models available in the market. The first option is known as the beam type and includes an elongated lever arm in between the head and the handle. When enough pressure is applied, the material bends flexibly. With this tool the indicator is fixed from a small bar at the head of the tool.
The other popular model of torque wrenches is known as the dual signal deflecting beam. With this option, pressure is applied to a deflecting beam unlike in the other models where a coil spring is used. This provides better readings and also makes it easier to use it. In addition, the tool has an audible and visual alert system when the right pressure has been applied.
