Abstract:
A method of captivating a fastener within a workpiece having a sleeve with an internal bore, the fastener having a threaded shank portion and an unthreaded shank portion each defining a given diameter, said method comprising:sliding the workpiece sleeve over the shank of the fastener such that the sleeve slides freely along the length of the fastener thereby forming a fastener pre-assembly; inwardly deforming a plurality of segments of the workpiece sleeve to create deformed segments, thereby reducing a portion of the internal bore size of the sleeve to a diameter less than that of the outer tips of the threads of the shank, and attaching a grommet to said workpiece sleeve; whereby the fastener can move axially relative to said sleeve diameter reduced portion about the unthreaded shank portion while engagement of the threads with the sleeve reduced diameter deformed segments prevents separation of the fastener from the workpiece.
