EHPro 3.1 screw dimensions?

[Flush1]

hey all. My EHPro 3.1 clone came missimg the airflow control screw, would anyone know what the dimensions for it would be so I can find a replacement at the hardware store? Filling sucks when you have to cover 2 holes...

I have no clue what the dimensions are but you could contact the vendor you got it from and ask them.
