4. Tightening to elastic limits (yield)
The bolt is tightened until its elastic limit is reached.
This method is used when each bolt must achieve the maximum clamping force. This method is seldom
used in the car industry (example: Connecting rods). It is more common in the aerospace industry.
These bolts are normally used in special applications and the shank of the bolt
is designed with a special thin section to be stretched (this bolt works as a
precise spring).
The next paragraphs explain in details how the STwrench performs these tightening methods.
Tightening with prevailing torque
The bolt is tightened in a joint having prevailing torque. The
STwrench compensates the prevailing torque in the target value.
