tightening torque

klucz dynamometryczny = torque wrench

Tightening torque results in clamping force.

A very common method for checking the tightening torque is to use a click wrench, which is a torque wrench equipped with a clutch that can be pre-adjusted to a specific torque. If the torque is greater than the preset torque value the clutch will release with a click.

Tightening Torque Guide for Grade 5 & 8 Hex Cap Screws
These Figures represent an estimate of torque (torque being the measurement of friction, not tension) required to induce given preload (clamp load) in a bolt for non-critical applications only. For critical or special applications where greater control is desired this should be experimentally determined. This applies to washer faced or double chamfered hex nuts (or bolts, if bolt is torqued) having a width across flats of approximately 1.5 times the nominal diameter and having threads free of interference.

Zac. jest skrótem od zacisku, czyli clamping, ale clamping load jest siłą, a kG-cm jest momentem obrotowym, czyli tightening torque.
