Zusammenfassung:A system for pre-tensioning a joint (13) including two or more threaded fasteners (11a - c) by a synchronized tightening of the threaded fasteners, comprising two or more torque delivering power wrenches (10a - c) and at least one operation control unit (18) communicating with the power wrenches for control of the operation of each one of the power wrenches, wherein the power wrenches are manually supported battery powered power wrenches each having a wireless communication module, and that the operation control unit comprises a wireless communication module (24) for communicating with the wireless communication modules (16a - c)of the power wrenches to thereby receive actual operation data from each power wrench and to deliver relevant operation data to each power wenches to adapt the tightening operation of each power wrench to the actual tightening status of the other power wrench or wrenches to obtain a synchronous tightening of the fasteners and an even pre-tensioning of the joint.
