If it's threaded into aluminum,it's 6 x 1.0(coarse thread) coarse is almost always used on aluminum,unless it has an insert of some type.
Well for most things it's good enough. It's the Cliff Notes or Idiot's guide to a lot of topics and summarizes most things well. But definitely not comprehensive enough on technical items. Engineers aren't the best at writing and they spend enough time doing it for their projects that they certainly aren't going to spend extra time doing it for free.
One of the issues with that Wiki article on threads is it's theoretical. Real-world threads are cut and rolled with a more rounded profile and have a pre-determined gap between the male & female threads to allow for production variations. This gap varies based upon the size of the fasteners and their material.
I had one heck of a time finding M7 12-point bolts at a hardware store out in the middle of nowhere.
