1. A collet body for a single-side fastening system comprising:
a cylindrical wall portion positioned at an upper end of the collet body and defining a longitudinal axis and having a threaded inner surface and an outer surface which has a circular shape in cross-section that cuts through the longitudinal axis; and
one or more gripping fingers extended longitudinally from the cylindrical wall portion and separated by one or more slots, each finger having a protrusion at a fingertip, the protrusion comprising a leading surface and a trailing surface, the one or more gripping fingers being flexible in a radial direction and biased to converge radially inward with the protrusion of each gripping finger within a radial area defined by the cylindrical wall portion, the one or more gripping fingers diverging radially outward when pushed radially outward to cause the protrusion(s) of the one or more gripping fingers beyond the radial area defined by the cylindrical wall portion;
wherein the one or more slots and the one or more gripping fingers are profiled to interact with a sleeve insert or a clip to prevent rotation of the collet body in relation to the sleeve insert or the clip.
