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

Filister head self tapping screws

Not "sheet metal screws"

Gunner


Thanks but I'm not sure they are what I'm looking for. I googled
"filister head...." and it only seems to point to screws with the common
coarse / sharp self tapping thread. I think the filister bit refers to
the bulging pan head style.


I was wrong...flipped my mouth off without thinking..sorry

"Countersunk" head.

The "Self Taping Screw/bolt" though is correct.

Also known as a "self taping machine screw" Also "Thread Cutting
Screws"
