2.5"/Laptop HDD screw length

[sm0ke]

My girl's MacBook Pro has some power issue and it's not turning on. I need to hook the hard drive up to my desktop to get some school work off of it. I know I need M3 screws, but I'm not sure what length I need or how much it matters.

I got the MacBook from an Apple store in December 2011, and the HDD is a SeaGate Momentus 5400.6

Any help would be appreciated.
