A tie-down anchor is secured to a threaded stud projecting from a surface inside an auto to provide a point of attachment for a flexible member such as a cord or loop of a cargo restraint net. The anchor has a tubular stem defining an axial through hole for receiving the stud, and a plurality of barbs extending radially inward into the through hole and angled along the axis of the through hole in the direction in which the stud is inserted. The anchor is pushed directly onto the stud, the barbs deflecting radially outward as the stud is inserted into the through hole. The tips of the barbs engage the threads in a ratcheting manner as the stud is inserted into the through hole. The angled barbs effectively prevent withdrawal from the through hole unless the anchor is rotated to unthread it from the stud. The through hole allows the anchor to be produced as a single, integral piece requiring no further assembly before it is installed in connection with a threaded stud. A plurality of axial ridges are formed about the circumference of the through hole and offset from the barbs to define an inside diameter approximately equal to the outside diameter of the stud. The ridges contact the outer surface of the stud along substantially the entire length of the stem to provide a secure and stable engagement between the components.
A push-on anchor for mating engagement with a stud having an outer surface and threads formed thereon, the anchor comprising a stem having a retaining flange extending radially outward adjacent a first end thereof, an axial hole for receiving the stud, and means extending within the stem for engaging the threads as the stud is urged into the hole from a second end of the stem and resisting withdrawal of the stud from the second end of the stem, the anchor characterized in that:
