ABSTRACT:
A fastener assembly with a break mandrel blind rivet and a mating female component having head and tubular shank portions. The tubular shank includes major and minor bore sections and an intermediate internal shoulder. The blind rivet telescopes into the female component to provide a grip range. Positive axial draw-up between the rivet and component upon tensioning of the mandrel is achieved by engagement between and expanded area of the blind rivet and the internal shoulder of the femal component. The head of the female component has a central aperture for receiving the end of the mandrel to increase the grip range of the assembly. A plastic case molded around the head closes off the aperture and affords a weatherproof seal.
