Shark 250 Thread size and pitch of front brake caliper?

[jatgm12]

Would anyone happen to know the thread size and pitch of the front brake caliper on a shark 250 Enduro?
I lost them somehow. I also need them as stainless and with a flange I think. But I don't know the size and don't have one of those tools to check it that's like a keychain of offsets of a particular labeled size. If I know what size I can get it at the hardware store.
