ABSTRACT:
Disclosed is a composite fastener that includes a metal fastener having a shank with an entrant end and an integral insert. A bottom surface of the insert has a greater diameter than the diameter of the shank. The bottom surface also has a lip extending about the periphery of the shank, which during manufacturing of the composite fastener forms a seal against a shuttle for preventing molten material from running down the shank. Further, the insert includes a configuration for supporting a shuttle pin, such as shuttle pin receiving receptacle, to align the metal fastener in a shuttle. A non-corrosive head made of the extrudable material, such as zinc, encapsulates the insert. A method for manufacturing the composite fastener is also disclosed.
