BLIND FASTENER WARREN F. DAHL AND RICHARD C. LANDT ABSTRACT OF THE DISCLOSURE A blind fastener assembly includes, in one embodiment a pin, an expander and a sleeve. The pin and expander may in- clude, in one configuration, mating threads for drawing the sleeve axially over the expander toward the blind side of a work- piece, or the pin may be a pull-type wherein the portion of the pin opposite from the blind side end has pull grooves which are adapted to be gripped by a conventional pull gun. The sleeve is a tubular member with a portion of its length having a normal radial thickness and a portion having reduced radial thickness comprising a reduced outer diameter over a portion of its axial length and a counter-bore along the same axial length adjacent one end of the sleeve. The expander extends through aligned holes in the workpieces and has a tapered nose surface proximate the reduced thickness portion of the sleeve. When an axial force is exerted on the pin, the reduced thickness portion of the sleeve 18 forced over the tapered nose surface on the expand- er toward the blind side of the workpiece and is expanded in diameter. The tapered surface of the expander also deforms and - 1 - dependent on the overall joint thickness, with a large diameter bulb forming for a maximum joint thickness and a smaller diameter bulb being formed for a minimum joint thickness.
