The fastener is pulled through cooperating apertures in a stackup of parts being joined by a tool with jaws which can be closed to grip the pintail of the fastener and then retracted to seat the fastener. A collar is swaged onto a grooved section of the fastener's shank and the pintail is broken off to complete the installation of the fastener.
