Abstract (en)
[origin: WO2011007052A1] The present invention relates to a nut (6) for a moment screw, comprising an upper torsion member (1), a lower clamping member (2) of the same material with the torsion member (1). A weakening groove (3) is between the torsion member and the clamping member, the weakening part (3) being dimensioned so as to establish a fraction point between the torsion member and the clamping member as a given torque occurs between the torsion member and the clamping member. The lower clamping member (2) has its thread (4) continue across the fraction point (3) of the nut (6) to a bottom edge or bottom part of the torsion member (1).
