ABSTRACT:
A blind fastener that is installed from one side only of a hole in a plate structure wherein the blind fastener has a tubular body with a head and an inset loosely journaled in the central bore of such tubular body. A roll pin interconnects the tubular body and the insert to allow for limited vertical movement in a direction along the central axis of the central bore which in cooperation with the loose journaling of the insert within the central bore allows a floating action to the insert. The insert has a flange at its lowermost end for abuttingly engaging the lowermost annular edge of the tubular body to provide means for exerting forces on the tubular body to upset such tubular body.
