What is it
Verifies tightening torque with torque wrench according to manufacturer specifications or standard.
Why is it done
Prevents false contacts, loosening from vibration, and overheating from poor tightening.
How is it done
- Instrument: calibrated torque wrench (adequate range).
- Apply torque to target value in correct direction; record and re-tighten if necessary.
- Use manufacturer table and consider temperature/terminal material.
Expected results
- Torque within ± manufacturer tolerance.
- Discrepancies → check threads/terminals, possible terminal replacement.
