When I want to use a barrel stub as a "Power screw" I will keep that info in mind. Buttress threads are pretty much used in applications where you want to "Lock" but not "Lock up". Takedown gun barrels, cannon breeches, adjustable wrenches, ect. Technology? If you follow military gun production over the years it is easy to see that the screws and threads became finer and finer. The truth is early shops had a hard time with thread making. Early machine screws on guns are so course they look like wood screws.
