The male component (10) of a press-stud has a dome (11) that extends, so as to form an undercut region (14), from a first base (15) that is formed by blanking and plastic deformation from a metal plate. An intermediate tubular element (12), which is also formed by blanking and plastic deformation from a metal plate, is inserted axially in the dome, affecting part of its internal extension. The intermediate tubular element (12) extends from a second base (16) to be seamed to the first base (15) by folding the perimetric edge of the first base (15). A stem (13) protrudes from a third base (17) and has such a cross-section and length as to pass through the intermediate element (12), perforating the fabric (20) to which the male component (10) of the press-stud is fixed, and to deform against the dome (11), interposing a wider region between the dome (11) and the end of the intermediate element (12). <IMAGE> |
