| Value Type | PMTechValue |
The sinking depth at the internal thread tS increases the clamping length lK, thereby increasing, for example, the length of the free loaded thread lGew and thus the resilience δGew of the bolt and δP of the clamped parts. In addition, care must be taken that the screwed-in thread does not become too short.
