Buy lead anchors a little larger than the screws you want to use. Ask for a masonry bit for an electric drill just the size of your lead anchor. Drill hole, slide in the tube shaped anchor, then use screwdriver to screw the threaded screw into the lead anchor. The anchor will expand as the screw goes in, thus holding tightly to the concrete.





TapCon screws do work (previous answer from someone else) but usually require a powerful drill to drive into concrete.





I built a all concrete house and we used a 'hammer drill' or pneumatic drill to drive TapCon screws. Not something usually around the house. See link to concrete house below.
go to a hardware store ask for Tap cons, tell them what your doing, they can give you the right size and explain how to use them


its a screw made to use in cement, you have to drill a hole first then just screw the Tap in
