ABSTRACT:
A fastener for removably securing a plurality of panels includes a stud member having a top turning means, such as a flat handle, a central shank portion and a bottom camming (knob) portion. The fastener, upon being rotated, is moved along its axis by ramp means secured to a panel. The camming portion acts against the internal walls of spreadable flexible finger members to spread them outwardly and thereby grip the other panel.
