I decided to install a tool grid in my metric wrench drawer. Matco and Cornwell both sell grids sized to their toolbox drawers. I have a snapon toolbox so I got a grid from Cornwell that was close and cut it to fit. Lay out the holders how you want on the board and then screw them down. They also have clips for sockets and other tools. This is by far the best organizer I have ever had. It might be cost prohibitive for a DIY but its money well spent for a pro. Honestly dont know what I paid, went on my revolving account
