I'd like to see the development of these on a timeline, including the rise of power tools. I suspect that hex, torx, and similar are only feasible due to torque-control being available on modern driving tools; prior to that the screw had to be able to disengage (cam out) to prevent it breaking.
- rwbcxrz 9y agoYou might enjoy this article from about 6 months ago (as I did). It doesn't get into torx or hex drives, but covers quite a bit of history of Phillips-like drives. http://www.instructables.com/id/When-a-Phillips-is-not-a-Phillips/ http://www.instructables.com/id/When-a-Phillips-is-not-a-Phi...

- dugditches 9y agoThis touches on what you're talking about. If you have the time the entire video's a gem of history screw history touching on Nails going into screw coatings, drives, etc. https://www.youtube.com/watch?v=N3jG5xtSQAo#t=5m05s https://www.youtube.com/watch?v=N3jG5xtSQAo#t=5m05s
