I need more storage and am going to add some firing strips and plywood to the walls around my bench. Currently just block wall as it is a basement shop. I did some googling and it seems these Tapcon fasteners are getting good reviews. Anyone have any experience here. I am planning to add a plane and saw till plus some other tools hung in their individual hangers. To be clear I am speaking of the blue screws that get screwed directly into a hole drilled in the blocks. Not some form of lead or plastic anchor. Thanks, John..
