Probably some Bozo replaced that screw with a 6-32 UNC machine screw.

That screw should be an M3.5-0.6 (metric) machine screw.

In order to restore the threads, you're going to need a M3.5-0.6 tap, which 
is about as scarce as hen's teeth, but is available from the larger machine 
tool supply houses (Enco, MSC, J&L, etcetera).

Might as well get an M3.5-0.6 die at the same time, so you can restore the 
threads on any M3.5-0.6 fasteners which were mistakenly driven into 6-32 UNC 
holes, such as found on disk drives.

Many a G3 case has been ruined by using 6-32 UNC screws to retain PCI cards. 
Those retention screws are indeed 6-32 UNC on PCs, but on all Macs with PCI 
card retention screws, those are also M3.5-0.6, in an interesting deviation 
of the PCI spec.

Bottom line, the Mac is now, and has always been all "all Metric" product.
