Abstract: An adhesively secured anchor rod for installation in a bore of a concrete base, pad, or the like, and comprising a bar having a first threaded portion of a standard thread provided at one end thereof, a second threaded portion of a coarse or coil thread provided at the opposite end thereof, and an intermediate threaded portion of a coarse or coil thread interposed therebetween, the length of the first threaded portion being selected to provide a gauge for determining the depth of embedding for the anchor rod within the concrete base, and the direction of the threads of the second threaded portion and intermediate portion being reversed with respect to each other for facilitating mixing of the components of an adhesive material placed within the bore and increasing resistance of the anchor rod against accidental "backing out" of the rod from the bore subsequent to installation thereof, the outer end of the second threaded portion being provided with recesses for facilitating the entering of the adhesive materi
