Hydrowizard 63 honeycomb cage replacement screw size

[jt17]

I did a bonehead move and mistakenly washed the screws for the cage down the drain. These were the screws that held the cage together and not the larger screws that connect the cage to the pump. Does anyone know what size those screws are?
