A bolt left too loose can let a component move; one tightened too far can damage threads or parts. For a stem, seat clamp or other joint, use the relevant manufacturer’s torque specification rather than one universal number. A torque wrench measures resistance to turning, but it cannot fix a bolt started across its threads.
On a click-type wrench, the sound may be faint at lower settings. Park Tool explains that movement of the wrench head is the signal: once it deflects, the set torque has been reached and tightening should stop. Seat the bit fully in the bolt, then apply slow, steady force with your hand in the intended position on the handle.
After use, this kind of wrench should be wound down to the lowest value on its scale, rather than zero, to relieve its spring. Impacts and misuse can affect accuracy. The right tool helps, but a sound joint also depends on undamaged threads and the instructions for the exact component.
