M3-0.5 are ISO standard and are available everywhere, although not in all lengths and in all screw head types. M3.5-0.6 is a now obsolete screw which Apple adopted in 1984 (while this size was still a quasi-standard) and Apple needed a metric screw with the approximate holding capacity (under tension and shear) of a 6-32 UNC. The M3.5-0.6 was selected as this was the closest metric size with the required physical characteristics. I know of no other equipment, besides Apple, which still uses the M3.5-0.6. Right now, there is a large "void" in metric machine screws, between the M3, with the approximate holding capacity (under tension and shear) of a 4-40 UNC, and the M4, with the approximate holding capacity (under tension and shear) of an 8-32 UNC. Meanwhile, the 6-32 UNC machine screw is just about the de-facto standard for most purposes, including retention of PCI cards, retention of disk drives, and retention of motherboards, power supplies and other case components. One of the few applications for the 4-40 UNC is D-Subminiature connectors. -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
