Abstract
A tacking fastener for securing workpieces together to form a temporary assembly includes a stem and an elongated sleeve. The stem includes a head disposed at a proximal end portion, a tapered portion extending between the proximal end portion and a central portion, a break notch extending around a circumference of the proximal end portion between the head and the tapered portion, and a plurality of ridges and grooves disposed along a distal end portion. The elongated sleeve is disposed around the stem between the head and the plurality of ridges and grooves and configured to form a tacking rivet upon installation of the tacking fastener. The elongated sleeve is plastically deformed during installation to form a plurality of bulbs, thereby being capable of securing workpieces of varying grip length. The stem and the tacking rivet remain within the workpieces after the workpieces are secured.
