ABSTRACT:
A releasable fastening device for securing workpieces together in a firm and intimate relationship is disclosed. The fastening device is sometimes referred to as a "blind fastener". The fastener comprises a bolt member including a head located on one end of the bolt and extending outwardly therefrom to support an upper workpiece and a shank with an annular recess, the shank being insertable within said through axially aligned apertures located in the workpieces. An expandable device, preferably in the form of a stiff spring is inserted and is confined within the annular recess. When the spring is in its expanded position, it extends beyond the shank along a bottom surface of a lower workpiece thereby along with the head on the bolt member holding the workpieces together in a mating relationship. A mechanism is included which releasably engages the spring and is capable of limiting the springs extension to within the annular recess to thereby allow the fastener to be inserted and withdrawn through the align apertures in the workpieces.
