Abstract: A snap fastener assembly includes a cylindrical C-shaped spring retainer member having a hollow open core with an exterior longitudinal slit aperture extending into the core. The spring retainer member is mounted on a stud member having an enlarged head at one end, a retaining head at the other end, and a longitudinal shaft that is dimensioned to be substantially enclosed by the spring retainer member. The stud member can be used for both the insertion and retraction of the cylindrical spring retainer member. The retainer member can be actively fastened to a hole, for example, to hold panels on a wall.
