<p>A two piece hand-manipulated variable fit fastener comprises an elongated fastener member (20) having a reduced axially extending portion permitting the fastener member to be folded on itself prior to being inserted through or withdrawn from aligned apertures (28) located in a pair of mating work pieces (30, 32) and a retainer element (26) having a plurality of locking surfaces, the retainer element being slidably mounted on the fastener member. After insertion through the aligned apertures in the work pieces, the fastener member (20) is unfolded to a position engaging one of the locking surfaces in the retainer element to lock the fastener member in a selected unfolded position depending on the diameter of the apertures (28). The positioning of the fastener member in the unfolded position also allows pairs of end shoulder portions (22) to engage one of the work pieces and the retainer element (26) to fasten the work pieces together. </p> |
