French cleat workshop bin

This is a general purpose bin for my French cleat wall. The cleat connects to the bin with 2 M4 x 20mm screws and nuts. The nuts are easily recessed into the cleat the help of an M4 screw and washer. Without the bin attached, use a screw and washer to pull the nut into the recess until it finds the bottom of the socket. Then back out the screw and discard the washer.
