The advantages of the hydraulic pretension mechanism tools come to use equally in all fields of application. With the screw tensioning devises and hydraulic nuts, connections can be tightened with the highest degree of accuracy and protocolled with greatest accuracy. During pure axial pretension force creation, no torsion force occurs, the screws are not subjected to force and twisting does not stress the bolts.
