Abstract
The member is in the form of a hollow body having a skirt (2) surmounted by a head (1), the entire body exhibiting circular symmetry about an axis (10). The hollow body has an internal ring (5) at an intermediate level between the head and the skirt. The surface of the internal ring is corrugated as traced by a generator line at a constant angle to said axis and moving around a closed corrugated curve situated in a plane orthogonal to said axis. This arrangement provides resistance to torsion forces without requiring any sharp inside edges that are difficult to manufacture in tempered glass.
