Tips for Selecting the Proper Torque Wrench
Before choosing a torque wench you need to understand the different types of wrench on the market and how they might best suit the needs of the user.
With production or assembly environments the torque setting is often at one specified torque which makes it easy to use a preset type of wrench. This is one where the wrench is supplied already set at a predetermined torque setting and is not user adjustable. This provides peace of mind in this environment as the torque setting can’t be accidently changed causing failures from incorrect assembly.
If on the other hand there is a need for an adjustable torque wrench then the user will need to decide on the range that will need to be covered as well as the scale to be used such as Nm or FtLb as not all wrenches come with dual scales.
Consideration also needs to be given to the type of tool, which may need to be a dial indicating tool for audit purposes, a breaking or bending action tool or the more common click style wrench.
The number of cycles the tool is subjected to in a year should form part of the equation as the tool will need to perform under these conditions without failure or calibration drift.
When all conditions are considered then the tool should reliably fulfil its intended purpose for a long time to come.
