I am using them (tek) as a bit to open holes when I don´t have a common bit and works very good in many cases.

[@McGuireMechanism]

Nice! They are such a useful fastener.

I thought self tapping screws do not require a pilot hole. I am aware I am mistaken after watching this video.

Hi Tuolite - terminology does vary from region to region and company to company, but these definitions are what I have found to be most standard. It is how they are classified in the McMaster-Carr catalog, for example.
