ABSTRACT:
A fastener delivery tube (21) incorporates an internal guide (22)--such as a continuous sleeve lining, flexible, or resiliently deformable spring strips (34, 37, 38) or re-circulating balls (54)--forming a longitudinally movable constriction, inhibiting fastener free-fall through the tube and preserving fastener orientation, by maintaining fastener (25) contact with a driving plunger (28) in its passage there-through and upon exit there-from into contact with a workpiece.
