<p>A nose assembly (8) attachable to an actuating tool (10) for pulling a pin type fastener (39) through aligned holes (49) in two or more workpieces (46,47) includes a pin-engagement jaw structure (37) that is locked to or unlocked from the fastener through a lost motion connection. A transverse pin (67,67A) that extends radially through a rear portion of the jaw structure and into an axial groove (71) in an annular housing (16) functions in response to axial motion of a collet member (22) that is operated within the housing by a reciprocable piston (14) in the actuation tool. <IMAGE></p> |
