ABSTRACT:
A construction anchor for mounting an object on a structure of masonry, concrete, metal or the like includes a metal anchoring portion and a plastic cap. The anchor is adapted to be inserted, metal end first, into a pre-drilled adhesive-filled hole. The cap has a flange that is larger than the hole diameter, so that the anchor may be inserted and seated in the hole at a consistent depth. When the adhesive has set, a screw or bolt is inserted through the plastic cap to engage the threads in an internal bore in the anchoring portion. The plastic cap serves not only to determine the depth of the anchor in the hole, but also to prevent adhesive and other material from entering the threaded interior of the anchor prior to use.
