Product Information

A torque wrench is an essential tool for mechanics and DIY enthusiasts, used to apply a precise amount of torque to a fastener such as a nut or bolt. However, over time and with regular use, a torque wrench may lose its accuracy. To ensure it remains reliable and delivers consistent results, it’s important to calibrate the torque wrench regularly. In this article, we’ll walk you through a step-by-step guide on how to calibrate your torque wrench. Typical load during torque wrench operation is another factor determining the frequency of calibration. A general rule of thumb often followed by technicians and workshops is not to use the torque wrench for more than 80% of its maximum torque value i.e. if the maximum torque limit on your torque wrench is 100 N.m, it is advisable not to use it for torqueing bolts and screws requiring a torque of more than 80 N.m. If you are using the torque wrench more often near its peak value, it may require calibration earlier than if you were using it in say 50% of its range. However, for certain circumstances, you may instead need to apply the ‘installation torque’ (Tinst) using a calibrated torque wrench. This figure be found in the ETA document or printed on the box.

Torque wrench calibration is required because torque wrenches have the tendency to lose their accuracy over time as the internal mechanism of a torque wrench is mechanical in nature that requires adjustment after certain period of use. An uncalibrated torque wrench is not trustworthy because you never know the torque at which it is tightening the fastener and that completely kills the intended purpose of using a torque wrench which is to make sure no overtightening or under-tightening is taking place. Regular torque wrench calibration is necessary to maintain the tool’s accuracy and prolong its lifespan, ensuring reliable performance. Tools Required for Calibration Why do you need a calibrated torque wrench to correctly install anchors (thoughbolts, concrete screws & even drop-in anchors)?Used widely in a range of professional trades, car mechanics regularly use torque wrenches when servicing or repairing vehicles. Every fixing in a car has a specified torque value that needs to be met for safe use. And each type of vehicle has unique torque specifications that must be followed to prevent damage.

You’ll need this when installing concrete screws manually, and there are two scenarios where manual installation would be preferred (according to the Construction Fixings Association):Torque wrenches allow you to measure and limit the amount of force applied to a fixing. Every nut and bolt in your car will have a torque value. It’s particularly important that you have a torque wrench to hand if you’re working on the engine, gearbox or any crucial components in the drivetrain or suspension system. The above factors determine periodic calibration frequency of torque wrenches, however, there can be certain occurrences that necessitate calibration separately from the periodic calibration. Such factors include, Hydraulic - Used in heavy-duty applications, this type uses hydraulics to reach the torque required

It’ll have an analogue meter showing the amount of force being applied to the bolt. Watch the gauge carefully until it reaches the desired torque level, then stop applying force to the handle. Adjusting your torque wrench is a simple task that will go a long way in ensuring accurate and safe mechanical work. Remember to always keep your wrench maintained and calibrated for optimal results. Final ThoughtsCalibration is required to maintain the performance and accuracy of the tool. Torque wrenches apply force to tighten the screws, and it is essential to tighten them accurately. Because under-tightening and over-tightening can damage the plugs, a properly calibrated torque can help fasten the bolts accurately at a specific torque value. · Do New Torque Wrenches Need Calibration? Calibrating a torque wrench involves several steps that ensure the tool is functioning correctly and providing accurate readings. The first step is to inspect the tool visually for any damage or wear. Next, the torque wrench is tested to ensure it meets the manufacturer’s specifications. The calibration process involves using a torque calibration tester, a device that applies a known amount of force to the torque wrench.
