Drilled disks are not the same as vented discs anyway.

Vented are like 2 thin discs with spacers between them.
Drilled discs have holes drilled through the face.

I wouldn't use a threaded screw to block the hose, you run the risk of damaging the internal skin of the hose and the first you know is when you stamp on the peddle in a hurry and the peddle goes to the floor.
