I just lagged my wall into my concrete floor. I used a standard masonry bit and drilled the four holes I needed. I got the sleeve that I had and it had to be tapped into the hole cuz there built just a hair undersize. I dropped the sleve so it just barely went under the top of the concrete. Don't over crank either. You can break the anchor. I've lagged down machinary, but it would walk like an out of ballance dryer, not a car pullin sideways BTW go 5/8 anchors. Bigger is better. spent the extra 5$ at the depot.
