Claim:
A pulling head for installing fasteners, the fasteners selected from blind rivets, blind bolts, and lock bolts, said pulling head comprising: jaws symmetrically disposed about a longitudinal axis and adapted for gripping the fasteners; a jaw holder positioned about said jaws along said axis, said jaw holder having proximal means for joining said jaw holder to a spindle of a pulling tool and distal means for pressing said jaws against a fastener shaft, said jaw holder also having an external surface oriented lengthwise in a direction substantially parallel to said longitudinal axis and comprising at least one facet oriented lengthwise in a direction substantially parallel to said longitudinal axis, said facet spaced from said longitudinal axis by an edge distance; and an anvil sleeve positioned about said jaw holder and reciprocally slideable longitudinally relative to said jaw holder and reciprocally rotatable about said axis, said anvil sleeve including a proximal end adapted to mate with a pulling tool, a distal end adapted to swage fastener collars about fastener shafts, and a side opening extending to said distal end and sized such that the minimum distance between said axis and an exterior surface of said pulling head is substantially equal to said edge distance of said jaw holder.
