Why though? Do they think a pervert will go and unscrew doors? I’d argue the occupant would notice before it’s all unscrewed. Also, kicking it down might just be faster.
Cool concept though, but a person who loves repairing their stuff, I must say f it.
To elaborate: it’s in 3d, the s curve is a ramp. The regular screwdriver slots in when turned clockwise, but has no purchase the other way round. It slips out because the ramp lifts the screwdriver out of the screw.
What the actual fuck is a ‘S type’ screw? What purpose does that have that another normal screw type cannot provide? What madness is this?!
You can screw but can’t unscrew because it lifts the driver.
Easy to screw closed but not open. Gotta think about it in 3 dimensions. They are used in US bathroom stalls.

It’s less pervert prevention and more vandalism resistance.
I firmly believe that without these screws, there would actually be less vandalism. Because of theft.
I’ve seen them used in power supplies that are not supposed to be user-servicable.
