摘要： A fastening insert for concrete structures comprises a preferably tapered body member formed preferably of inexpensive, high density cellular plastic material which may be either conveniently molded or extruded into the desired shape for attachment to a concrete mold form to provide a readily accessible exposed base for selectively attaching fixtures or the like to the concrete structure after the mold form is removed. Molded through holes or apertured flanges may be provided to accept a nail or the like to secure the body member in position on the mold form during formation of the concrete structure. The base of the body member may be ridged, roughened, apertured, or dimpled to provide a plurality of selectively positioned recesses to aid in initiating the engagement of a threaded fastener therewith. Stabilizing means which may comprise rod-like extensions or flanged collars emanating from the body member may be provided to increase the interengagement between the body member and the surrounding concrete.
