Ohhh no… As a person who regularly builds random shit for film and television, the single slotted screw is the bane of my bloody existence. Some designers fucking love em for the aesthetic but the cam outs on them are terrible. Is it technically easier to produce? Yes, is it viable to use for construction purposes comparitively - fuck no. Every time you cam out ( lose traction on the screw) you risk accidentally damaging whatever medium you are screwing into.
Locally there is an insane institutional preference for the Robertson screw (which is basically a square) because it doesn’t cam out much, drives in well and arguably resists stripping better than a Phillips… This is believed in so much that any screw not seen by the camera is a Robby (usually size 2) while anything that is perceived by the audience is a phillips or a single slot screw. Given a choice nobody wants to handle single slots and chances are good you only find them in period specific builds or when the designer is a psychopath.
The only thing slotted was good for was on old ships. When water grime built up on them they were easy to scrape out with your screwdriver and use the screw. That is THE ONLY good thing about slotted screws. If they get full of shit it’s easy to clean out. Other than that they fucking suck in every other way.
