a range of preset torque adaptors and inserts it between the bit and the handle. In this way, the user can get accurate torque settings on sensitive fixings without breaking the bank – or the screwdriver!
Checking the Settings
Having been educated into some of the intricacies of torque tools recently, I know that torque tools have a life span during which they have to be regularly checked for accuracy and, if necessary, be recalibrated. Guarantees and warranties may depend on torque tools being accurately set, so it makes sense to have a system or even a tool that does informal and more regular checking of accurate torque settings. It could be very costly and time consuming to find out that a production tool is outside the torque parameters and then having to recall or recheck products. The Wiha solution is to use the Torque
QuickCheck that enables all Wiha screwdrivers to be checked for accuracy very regularly – before each use if needed. The checks are very easy to carry out – simply insert the screwdriver into the TorqueCheck and they will be checked at 2.8 Nm as a standard. If the TorqueCheck and the handle settings match up, then a green light will indicate that it is accurate. But a red or amber light would indicate an inaccuracy that would need further investigation and recalibration. The virtue of the QuickCheck system is that it is light, compact, accurate and could be slipped into a toolbox so that regular checking is not a chore. While it is not a substitute for recalibration, its use as a diagnostic tool that avoids expensive rechecks on jobs already completed is a cost-effective solution. I acknowledge that this is a swift and broad-brush overview of the range of Wiha torque tools. But I hope that it helps
readers to understand a few of the trends in torque tools available and the levels of sophistication that we have already reached in using torque applications. Like Brexit, torque applications aren’t going to go away, and end users will have to get to grips with the increasingly sophisticated systems in which torque tools are used.
Checks are very easy to carry out – simply insert the screwdriver into the TorqueCheck and they will be checked at 2.8 Nm as a standard.
Even your average ‘sparky’ and plumber these days needs to know torque settings for RCDs and boiler fittings. The Wiha range might be a good place to start looking at the tools needed.
