Can someone tell me what the size and thread pitch is for the screw that holds the sight to the frame on recent/current production J-frame?

Yes I know its stinking small.
Yes I know it might not be the most common size.
Yes I know I could call S&W but if you haven't done that lately, let me tell you its a 15+ minute hold time and deservers a rant...I mean thread of its own.

I just need numbers folks if you would be so kind. Thanks.

The front screw in my Model 34-1 is 3x56
