ABSTRACT:
Blind fastener of the type having a tubular outer member with a head at one end and a conical portion at the other end, the conical portion having its apex within the outer member. The conical portion is expanded radially to form a second head on the fastener for securing it in place. The member selected for expanding the conical portion comprises a spring pin. In some embodiments novel apex contacting means are interposed between the spring pin and the apex of the conical portion. The apex contacting means is either formed integrally with one end of the spring pin or as a separate piece disposed between the spring pin and the apex of the conical portion. One important advantage of using a spring pin as the setting means is that its resilience retains it within the outer member despite vibrations, temperature changes, or other conditions which might tend to dislodge the setting means. Other advantages are lighter weight and greater strength at no more cost than previous solid setting pins.
