What is the size and type of threading on the rear frame screws. I just received a NIB (And it clearly is a brand-new Micromag Rt valve) none of the 6 different frame screws which i have will thread into the valve threading. first-off, I guess I should make sure that the threading is the same as on every other AGD valve. I am pretty sure I would've heard of it was different, but you never really know. Anyways, assuming the threading is the same, what size and type is it, so I make sure to use the correct tapping die tomorrow when I get my tap and die set from my parents house. Also, has anyone ever had a problem like this with a brand-new valve? I thought it was a little odd myself. thanks guys
