Tool to screw slotted nuts

This is a helpful tool to fix "slotted nuts" on frontpanels. (works for the EZ1073 screws and potentiometers, not for alpha/lorlin rotary switches) "Slotted" means that there are two slots in the nut. Normally hexagon potetiometers screws are used, but if you don't want to see the edges of the hexagon nuts around the knobs... then slotted screws are the solution. They're also used on nearly every recording consoles, because they need less space. This tool makes it easily possible to screw these nuts without scratching the frontpanel.
