These brackets use an "L" shaped member that's permanently riveted to a 6mm pin.
The shelf itself forces the supports to stay put, no matter what the load.
The shafts of these supports have tapered ends (to simplify installation), and are 3/8" in length.
That's plenty long for a good "bite" into the cabinet sides, while allowing the possibility of having shelves on opposite sides of a 3/4" center partition.
Each bracket is 1/2" wide and projects into the cabinet a full 11/16", a very useful feature in case your shelves are a bit undersized!
