ABSTRACT:
A self-attaching fastener installation head and feed mechanism including a spring-biased L-shaped feed pawl which feeds a first nut in the feed passage adjacent the plunger passage on the upstroke of the die press. The feed pawl is pivotally supported on a slide bracket which includes a roller in the longitudinal axis of the feed passage which is biased against a central cam surface on the base and the base is interconnected to the nose member by removable pins. A spring biased nut restrictor is pivotally supported on the nose member, simplifying removal of a nut strip from the head and the installation head is more rugged in design and has fewer parts, reducing costs.
