I snapped 2 of the 6 screws for the wall mounting, like the title and numerous other reviews have said the mounting hardware is junk. They are using 3" cast aluminum screws for the mounting to the wall. The alignment is crucial as other have stated as well. My recommendation is to find the exact distance between studs and mount the brackets on the shelf the correct spacing and then remove it from the shelf and mount to the wall and then reattach to the shelf with the brackets holding the shelf in place.
