30mm scope ring screws

[Mcardenal]

Hello,

I was hoping to get a little guidance on the scope ring screws for a set of 30mm scope rings i want to recycle.

I had a heck of time removing the 8 screws that hold/clamp the rings together. I was finally able to get the rings apart and remove the older scope. However, the alan screw heads are now stripped. Does anyone know what the specs of the screws are?

Thanks

Martin
