For the TV, I drilled a pilot hole into the firing strips. Note the plans for our house state "3/4" rigid foam insulation" between 1" by 2" firing strips on 16 inch centers, with 1/2 plaster board on top. So there is 1.25 inches from the front surface of the wall to the concrete block which is more then enough for expanding wall anchors. As I recall, I used 1.25 inch lag bolts with a washer for the TV mount.

For smaller items like pictures, and medium to small pieces of framed art, I used 1 or 2 of the nail in hangers. I have used a better version of the expandable wall plugs (that were originally used in the closets), to rearrange the closets and the wireframe shelving.


Hope this helps.
