Abstract
A blind fastener assembly utilizes flexible legs extending from a cylindrical section of a spring pin. Gripping elements extend radially outwardly from the ends of the flexible legs. When the flexible legs and gripping elements are extended through an opening in the wall, a center pin can be pushed into the cylindrical portion to expand the flexible legs so that the gripping elements can engage the back of the wall. In one embodiment, removal of the center pin causes the flexible legs to contract whereupon the assembly can be removed from the wall.
