St80 tube ring bolts

[jnc71106]

Does anyone know what size bolts are needed for the st80 tube rings. I need the size of the bolts that go through the bottom of the rings and attach to the dovetail

I'm away from all my gear at the mo so I can't measure anything. But I need to order new ones

So if anyone can help out I would be very grateful

Thank you

Jake
