ABSTRACT:
An apparatus for form-locking torsion prevention in screw connections includes a bolt with a standard bolt thread and a special nut having a free end and nut threads. A thin-walled sheath is disposed on the free end of the special nut. An integral cross-sectional portion intended for deformation is in the form of a bead supported on the thin-walled sheath. The nut thread extends uninterruptedly through the sheath and the bead. The bolt thread extends through the bead. A thrust pad is pressed axially onto the bead and has a conically narrowing bore formed therein in which the bead is substantially radially plastically deformed and forced inward into the bolt thread.
