A tacking fastener for securing workpieces together to form a temporary assembly is provided that includes a stem and a sleeve. The stem includes a proximal end portion, a central portion, and a distal end portion. The stem further includes a head disposed at the proximal end portion, the head defining a distal face having a gripping feature. The sleeve includes a flange disposed at the distal end portion, the flange defining a proximal face having a gripping feature. The sleeve is disposed around the stem and configured to form a tacking rivet upon installation of the tacking fastener. The 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.

Blind, bulbing, tacking rivet and method of installation

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.
