I just did a set of cases where I installed Festool Systainer drawers. They used 5mm screws in the 32mm system holes. I'm now doing another shop cabinet using the 32mm system with conventional wood drawers. Do drawer guides like Grass accommodate 5mm screws and are they intended to go in the system holes? From looking at the KISS2 pdf, it looks like you can use the system holes.
