The selection and use of torque wrenches

One of the more frequently asked questions from our customers is “how do I select the correct torque wrench for application?” Generally, most torque wrenches are used for tightening nuts and bolts accurately. Nuts and bolts need varying degrees of accuracy depending on the materials being fastened together, and therefore, there are different wrenches for different applications. The two main reasons why we use torque wrenches are to achieve the correct level of tightness and then to ensure consistency across all of the bolts in the assembly. Used properly, a torque wrench will ensure that all bolts have the same level of torque applied. The effect of badly tightened bolts can be seen in lost time and money. It’s also worth noting that careless torque can cost lives. The most common torque wrench is called a click wrench. This wrench is used to tighten bolts and nuts and will indicate when a pre-set torque has been reached. The pre-set value can be set by the user, or by a quality control ...
