摘要： A method of making a knob (30) and ferrule (50) for a captive screw (10) is disclosed, the knob (30) integrally attached to the screw (10), the ferrule (50) attachable to a panel (60). The method of making the knob (30) includes providing an aluminum alloy base metal for the knob (30), pressing by cold-forming the base material into a generally cylindrical cup-shaped article (32) using at least one pressing operation, the cup having a generally cylindrical side wall (33), removing any base material situated outside of the perimeter of the cup-shaped article (32) and providing a hole in the bottom of the cup (32), coaxial with the hollow cylindrical walls (33) of the cup (32), thereby forming the knob (30).
