ABSTRACT:
Setting tool for setting fasteners by driving a pin into an opening of each fastener, comprising a split collet having a central opening through which the pin is driven, the abutting faces of the collet segments being functionally convex and the leading ends of their exterior surfaces defining outwardly opposed jaws. An O-ring encircling the collet urges the following ends of the collet segments together, thereby urging the jaws apart. A fastener can be inserted over the jaws to locate it for being set by the pin. In the illustrated structure at least a portion of the central opening of the collet is smaller than the shaft of the setting pin, so when the pin is thrust through the collet it spreads the segments apart, thereby more tightly engaging the interior wall of the fastener.
