Morning.

So I have a bit of a problem, I have a savage axis 2 in 30-06 that I could not get to group at all, scratching around a bit I found the obe scope ring baae to be a bit loose, wanting to tighten it I couldn't as the one head is stripped for some reason, I now want to replace the screws but I cant find the correct size for the screws or correct thread pitch,could someome maybe guide me in the right Direction, I am in South Africa so might be a challenge to get the correct parts, that is why I need to be sure of all the detail incase I need to special order?

Thanks in Advance.
