In a method for the documented tightening or tightening up of a heavily loaded screw connection of a threaded bolt and a nut screwed on the threaded bolt by using an axially operating tensioning device and a process control unit provided with a documentation module, the screw connection is identified by scanning an identification provided on the screw connection and data determined by scanning the identification is stored in the documentation module. The screw connection is lengthened by the tensioning device by axially pulling on a threaded end of the threaded bolt and a tightening force (FA) and/or a tightening pressure (PA) exerted by axially pulling on the threaded end is stored in the documentation module. After lengthening, the nut is turned by using a hand torque wrench and an actually exerted hand torque applied for turning the nut is stored in the documentation module.
