  1. Important to note the direction of forces to fasten the screw, specially in non-metalic: sloted and Phillips need a perpendicular force on top of the rotating force, Insufficient perpendicular force favors damage of the head. Important in hard to reach locations.

  2. Interesting subject, I am currently involved in the analysis of a complex assembly build and the most common specified fixing is a button head set screw, followed by a cap head. Obviously a button head is more user friendly due to it's lower profile but I imagine it would lack the ultimate head strength of a button head due to the reduced cross sectional area. A circular button or cap head will give a more uniform clamping force distribution, even when either a button or hex head is used with a washer. I know there is a limit to the size range offered with socket head screws so
