ABSTRACT:
A fastener installation head having a fastener receiving passage, a transverse plunger passage having a reciprocating plunger therein, a feed means feeding fasteners from the fastener passage beneath the plunger and a restrictor means preventing a fastener located ready for installation from withdrawing into the fastener passage. The restrictor means includes an arm pivotally connected to the fastener installation head having a finger resiliently biased into the fastener receiving passage, normally blocking withdrawal of a fastener from the ready location. The stop finger includes a camming face facing fasteners entering the plunger passage, whereby a fastener may enter the plunger passage upon actuation of the feed means but is prevented from withdrawing into the fastener passage.
