The element is assembled to the panel through a hole 18 in skin 10, of slightly smaller-diameter than ridge 19. Thus the panel snaps into the groove. The space around the shank is filled with a syntheticresin 21 which anchors in a groove 22 in the shank. The bottom of the groove may be deformed to form a thread-lock. In the case of stud B, the shank 32 is non- circular and has a groove 33. In another arrangement, a radially-disposed nylonplug constitutes the thread-lock, and the socket may be open from the head-end |
