SEALING CAP TUBULAR RIVET HEAD AND ASSEMBLY

摘要

A break mandrel fastener assembly that produces high axial draw-up action while affording wide grip range, quick installation, and one-side tightening. A fastener assembly with a break mandrel blind rivet (14) and a mating female component (13) having head (18) and tubular shank (19) portions. The tubular shank includes major and minor bore sections and an intermediate internal shoulder (29). The blind rivet (51) telescopes into the female component to provide a grip range. Positive axial draw-up between the rivet and component upon tensioning of the mandrel (52) is achieved by engagement between an expanded area of the blind rivet and the internal shoulder of the female component. The head (18) of the female component has a central aperture (32) for receiving the end of the mandrel to increase the grip range of the assembly. A plastic case (17) molded around the head closes off the aperture and affords a weatherproof seal.
