holding bracket screw identification

I lost one of the screws holding the ribbon cable holding bracket down over the screen and speaker cables while repairing my screen. I lost the larger of the three on the top right corner of the phone. I ordered a screw set but there was no way to id which screw goes where so I have 50 screws and no way to tell what screw is the right one. A picture or measurements of the screw to tell me the size would be appreciated. Any way to ID which screw I need would help.

The missing screw is the non-magnetized screw circled in orange. Labeled as 1.67 in second picture. Which screw is it?
