I dont know for sure my guess's would be that the machine threads the fine threaded & thinner thickness screws like used for HD's is for a better hold once tighten down, more vibration proof, smaller to be cheaper to make & sell & not weight as much to like shipping. Works cause one wall has more thickness HD for the threads to grab.
On framing or sheet metal screws the threads are course (heavy)& (wider apart from each other) & the threads are thicker also to grab the two thin walls of sheet metal which dont have much to grap onto. These screws also screw on faster to to save time, remember no cordless screwdrivers back then.
The other thing to consider is a screw that can hold a one pound device down is an overkill for devices weighing one ounce.
I also believe that a dual threaded & or just one size screw could be made & used for all PC screws the trick here is the threads inside the metal to be locked down must stay put or total to intermiten shorts would happen big time a nasty no no with electronics.
I am not an engineer but I have been down this road before myself.
