Embodiments of the present invention provide systems for connecting a floori ng system to a vertical wall. In one embodiment the building structure includes a floor comprising a cementitious slab and a wall supporting at least a portion of t he cementitious slab. A plurality of stand-off screws extend from the top of the wall into t he cementitious slab and are configured to transfer forces between the cementitious slab and the wall. The stand-off screws comprise a lower screw portion and an upper stand-off portion. The lower screw portion is drilled into the top of the wall, and the upper stand-off portion extends above the top of the wall and is encapsulated within the cementitious slab. In som e embodiments, at least a portion of the lower screw portion is heat treated to a higher degree of hardness relative to the remainder of the stand-off screw.
