ABSTRACT:
A high strength blind bolt for fastening structural workpieces the blind bolt being of a swage type, pull type construction and having a pin member with a plurality of locking grooves, a main sleeve, an expandable sleeve and a collar adapted to be swaged into the lock grooves, the main sleeve having a tapered nose portion adapted to radially expand the expandable sleeve in response to the application of a preselected relative axial force applied between the pin member and the collar, the tapered nose portion being defined by a preselected small angle to limit the radial expansion of the expandable sleeve to provide a high strength blind head for engaging the adjacent, blind side of the structural workpieces and to initially clamp the structural workpieces together at a high clamp load and to provide a final high, residual clamp load upon swaging of the collar into the lock grooves of the pin member.
