To evaluate the tightness or torque given to bottle caps and other closures, a bottle cap torque tester is a specialised tool. A bottle cap torque tester's main function is to gauge the amount of rotational power needed to open or close a bottle cap. It makes sure that the caps are properly tightened, avoiding leaks, contamination, and the deterioration of the packaged contents. Utilising calibrated torque standards or known weights, calibrations can be carried out.
