Current work method:
Using air impact or pulse wrench to tighten up to around 80% of final torque then use torque click wrench to tighten to 100% target torque with torque accuracy within ±5%~±10%
Possible risks on the current work method:
- Torque click wrench does not provide any visual signs or number readings, therefore it’s not possible to know or record the final result.
- Torque click wrench is not reliable as when it clicks, it does not mean the actual torque is within the target torque range
- Operating gestures on the torque click wrench may impact the final tighten result.
Example on the chassis assembly
Target torque range:
30Nm, 60Nm, 110Nm
170Nm, 260Nm, 295Nm
Target torque range:
30Nm, 60Nm, 110Nm
260Nm, 298Nm, 395Nm
460Nm, 650Nm, 750Nm

Proposed solution:
The wireless torque transducer adapt on click wrench will record the final tightened torque and shows the real time torque reading on each of the bolts with angle. Target specification with tolerance can be set up in the software and have all the records stored on the device or upload to the Cloud server.
Additional benefits:
- Prevent untightened bolt and counting the number of tightened bolts.
- Prevent re-hit / re-tighten the bolt with angle monitoring during the process
Advantages:
- Can be easily integrated to the work stations/processes by attach the wireless torque transducer to existing tools
- Cost saving and easy integration solution to enable extra insurances on each bolt tightening tasks while enjoy the benefits of following features from software provided.
- Real time tightening torque and judgement
- Records operator ID and can be controlled by personalize accounts or permissions
- Records work piece serial number
- Records actual torque
- Records tightened result
- Records work time
- Data logging and uploads to preferred Cloud server or destination
- Work parameters like target torque, quantity and tightened angle can be set up in advance to ensure no misses or errors
