What are these extra 4 screws for (H50) ?

[Cornholio]

Bought my H50 today from scan, got it all mounted up and im in love with it so far, might swap the fan out for one of my noctua's though, anyway back to the question.

In the packaging i had 8 screws that look like they mount the back plate/heatsink, 4 have a fine thread (which ive used to screw into the am3 back plate) and the other 4 are exactly the same apart from they have a corse thread ? Sorta like HDD screws but not as big of a pitch.

Any ideas guys ?

I think the intel and AMD have brackets have different threading and therefore different screws.

Those screws fit stock AMD back plates.

DOH, so i didnt need to remove the board ? I could of just used those screws ? I had a bit of trouble installing the pump, i had to completley remove the bracket in order to get it in and lock it in, then screw the bracket down.
