Abstract
A tack button utilizes a pivot tack that has a long taper on its shank which prevents buckling and a subsequent loose connection of the assembled button parts, particularly the assembly of the back member of the button with the fabric to which the button is being attached. The long tapered shank curls as the assembly process is carried out so that a curled structure is within the button shell and is positioned to clinch the back member to the fabric.
