Those are some really theoretical ways to observe a clock face.
How about we just start saying, “torque in, torque out”? When the torque vector points in, the screw goes in (tightening). When it points out, the screw comes out (loosening). As long as you are standing on the side of the screw you can actually work with while working with it (and why wouldn’t you be?) this is never ambiguous.
Of course, now we’re kicking the can down the road and relying on people wrapping their heads around the right hand rule… Hmm…
