    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?!

      Easy to screw closed but not open. Gotta think about it in 3 dimensions. They are used in US bathroom stalls.

        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 as 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.

      It appears to be a security screw, where this chart doesn’t show depth. The walls of the s are slanted so you can only tighten the screw.
