ABSTRACT:
A self-sealing expansion rivet assembly comprises an expandable hollow plastic rivet and a plastic drive pin therefor. The rivet has a head and a slotted expandable shank for insertion in aligned holes in sheets which are to be joined together. The drive pin has a head and a serrated shank which, when inserted in the rivet bore and axially drawn thereinto by a tool, causes the pin head to engage the insertion end of the rivet shank and effect outward expansion of the rivet shank to fasten the sheets together, as well as break-off of the projecting end of the pin shank. The pin shank serrations engage a serrated reduced-bore portion in the rivet to hold the pin and rivet together permanently. Integrally formed annularly-shaped conical flexible liquid sealing flanges are provided on the rivet on, at or near the rivet head. As the rivet is expanded by the tool, the sealing flanges are forced against the adjacent panel around the hole therethrough to form a leak-proof seal.
