ABSTRACT:
A construction anchor for mounting an object on a structure of masonry, concrete, wood, metal or the like includes an anchoring portion and a cap. The anchor is adapted to be inserted, anchoring portion first into a pre-drilled adhesive-filled hole. The anchoring portion has a threaded bore, which includes an unthreaded close-fit-counterbore portion outward of a threaded portion. The cap prevents dust, dirt and adhesive from entering the threaded bore, and has an upper surface with a removable central area. When the adhesive has set, holding the construction anchor within the hole, the central area is removed, and a screw or bolt is inserted through the hole left by the removal and engaged with the threaded portion of the threaded bore. The unthreaded close-fit-counterbore portion of the threaded bore provides a stretch zone for the screw or bolt.
