All internal screw sizes for A1398?

I'm wondering if anyone knows what screw threading and length I need to replace... ALL of the internal screws in this particular laptop (a1398).

I do mean everything...
-Logic board hold-down screws

-Fan screws

-Hinge screws (I believe they're stainless)

-SSD hold-down screw.

-Processor clip screws (important, I only have 3 of them!)

If the threading is the same for everything? I can get a kit of various lengths if they're some standard M threading.

Someone attempted to repair the %#*@ laptop and absolutely butchered it... now it's my attempt.

Cheers!
