Abstract
A solid wall plug-type anchor comprised of a molded extrudible plastic material comprises a central hinge section and at least two extension members longitudinally extending from the hinge section. The hinge section permits the extension members to be hingedly moved into engaging nested juxtaposition with each other with nesting of integrally formed depressions and elevations in the engaging surfaces of the extension members. The nested structure comprises a solid, solid-wall elongated anchor with the hinge section at one end of the anchor and with the juxtaposed free ends of the extension members comprising another end of the anchor. The extension members each further comprises a plurality of small, non-contiguous wells which remain open within the nested extension members but which wells are not externally exposed. The wells provide stress relief for the anchor when a large screw or bolt is longitudinally inserted therein by providing a measured initial accommodation of extruded plastic during the screw insertion into a substantially solid interface between the extension members. The free ends of the extension members form a cavity for initial guided insertion of the screw or bolt.
