A plastic hollow wall anchor having folding arms for insertion within a limited diameter aperture in a substrate such as a wall. The arms, adjacent their overlapping attachment areas, are configured to provide a "sharp knife edge" intersection, whereby a spacing between the attached arms, during folding and aperture insertion, is substantially eliminated. The load bearing arms are concomitantly thickened and thereby strengthened within the limited dimension afforded by the aperture. Alternatively, the overall dimensions of the anchor are reduced, while maintaining the load bearing arm dimensions, thereby enabling the use of a smaller diameter for the insertion aperture without decrease in anchor holding strength. |
