An anchor assembly capable of being inserted in a hole in a substrate. The assembly includes a sleeve and a screw. The sleeve includes a top end, a body portion, and a bottom end. The sleeve includes at least one feeler prong adjacent the top end, and preferably a tip portion adjacent the bottom end. The anchor assembly may be inserted into a hole in the substrate. The feeler prong(s) enable the installer to known whether the sleeve has been inserted properly into the hole, and the tip serves to push dust away from the bottom of a hole to insure optimum penetration of the sleeve into the hole, as well as insuring full penetration of the screw into the sleeve.
