Default What are these self tapping screws called that form "real" threads?

Techman, I think you're not 'getting it'.

Even our CONSUMER big-box hardwares carry just what you want. Home Depot
(of all places) carries M4-0.7 self-tapping screws.

What you describe as "coarse-thread self-tappers" are truly "sheet metal
screws".
