Zusammenfassung:A fastener tensioning method wherein pre-tensioning fastener tightening history acquired during the tightening of the fastener prior to the point of proportional tensioning of the fastener is utilized to modify the tightening cycle occurring after the point of proportional fastener tensioning to reduce the resultant tension scatter while using a tightening perimeter such as torque as an indicator of fastener tension.
