ABSTRACT:
A pull-type blind fastener has a pin slideable through a tubular selectively annealed sleeve, the pin having a pin head permanently bonded to a blind side end of the sleeve, a hollow rivet head formed on the opposite end of the sleeve, and a raised abutment on the rivet head engageable by a conventional rivet setting tool. The rivet head collapses under the differential pulling force applied by the setting tool to a condition of reduced aperture for engaging a stop shoulder on the pin thus limiting axial pin travel at a flush breaking position.
