Abstract:
1. A blind rivet comprising a body including a longitudinally elongated and hollow main body segment, which is deformable in a laterally expanded direction, and a laterally enlarged head, the main segment further including an outer surface having at least one longitudinally elongated indentation having a longitudinally oriented slit extending therethrough, a majority of the indentation being defined by tapered surfaces that are substantially planar and extend between the outer surface and an inner surface of the main body segment, a mandrel including a longitudinally elongated shaft and a laterally enlarged segment, at least a portion of the shaft being located within the main body segment and having an indentation, the main body segment including an inwardly extending flange partially positioned within the indentation of the mandrel to couple the mandrel to the body, disposed adjacent to the longitudinally elongated indentation is a column, said column being outwardly bulged away from the mandrel when the rivet is in an unset configuration; wherein the indentation at each longitudinal end of the slit is formed by a substantially planar inclined end surface, each of said planar end surfaces being bounded by three boundary edges, two of said edges terminating together at an intersection with the end of the slit.
