Metric Self-Tapping screws 1

[SteveSmith]

I am trying to find what are the standard sizes and lengths of metric self-tapping sheet metal screws. So far I have found very little. At the Rittal web site I found what they call a "BZ 5.5 x 13 Muli-tooth Screw" for 4.5mm holes.

Can anyone guide me to a decent website on this? Thanks in advanced.
