Abstract: The invention concerns a tool (1), a method and use of such a tool (1) for mounting stud bolts (12). The tool (1) is intended for use in connection with a drive, preferably a hand held drive, and is provided with a threaded part (4) that interacts with the threaded end (14) of the stud bolt during mounting of the stud bolt (12). The threaded part (4) is the part forming mechanical connection to a stud bolt (12) and which during mounting of the stud bolt (12) serves as operating measure. In a preferred variant of a tool (1) according to the invention, the threaded part (4) is made conical. By making a conical screw thread there is achieved the advantage that the engagement between stud bolt (12) and tool (1) is imparted low frictional resistance.
