ABSTRACT:
A two piece hand-manipulated variable fit fastener is disclosed comprising an elongated fastener member having a reduced axially extending portion permitting the fastener member to be folded on itself prior to being inserted through aligned apertures located in a pair of mating surfaces and a retainer element having a plurality of locking surfaces, the retainer element being slidably mounted on the fastener member. After insertion through the aligned apertures in the mating surfaces, the fastener element is unfolded to a position engaging one of the locking surfaces in the retainer element to lock the fastener member in the unfolded position. The positioning of the fastener member in the unfolded position also allows a pair of end shoulder portions to engage one of the mating surfaces and the retainer element to fasten the mating surfaces together.
