The grommet includes a shank with a planar surface through which an aperture is formed. A screw is inserted into the aperture. Boss segments are formed peripherally outwardly adjacent from the aperture. The outer walls of the boss segments form a diameter equal to the diameter of an aperture of a secondary panel to be engaged. The diameter of the screw head does not exceed the diameter of the aperture to be engaged. When the screw is in the fully driven position, the lower chamfered surface of the head of the screw urges the boss segments outwardly so as to engage the secondary panel. The shank of the grommet further includes lateral flexible wings for detent engaging a primary panel with a square aperture.
