The Socket Button Head Screw design is primarily used where a lower profile head is required and for aesthetical reasons.
These screws can take a lower tightening torque as compared to the DIN 912 screws.

Socket set screws offer three types of holding power: torsional (resistance to rotation); axial (resistance to lateral movement); and vibrational. Size selection is an important factor in holding power.

The cup point is the most commonly used point style. It is used for the fast permanent or semi-permanent assembly of parts such as collars, pulleys, gears or bearings on shafting of hardness up to within 10 to 15 Rockwell C points of the screw hardness and where the digging in of the point is not undesirable.

Flat head screws are used for flush mounting of sections, usually where one part slides over another or one part is mounted on another.  Flat head screws, like button heads and low heads, are limited by configuration in their tensile strength capability.  Because of this, they should not be used in applications requiring full strength, where Socket Head Cap Screws should be used.

These are high strength, precision fasteners that are designed to be used in applications where head height clearance is a problem. Because of their reduced head height and smaller socket size, they normally cannot be preloaded as high as a standard socket head cap screw and should not be subjected to high dynamic loads.
Suitable for use in parts too thin for standard height socket cap screw and for applications with limited clearances 

Socket caps have a small cylindrical head with tall vertical sides. Allen (hex socket) drive is a six-sided recess[Internal Hex Socket] for use with an allen wrench (hex key).
This design is the workhorse of the machine building industry.
The most important reasons for the increasing use of socket head cap screws in industry are safety, reliability and economy. All three reasons are directly traceable to the superior performance of socket screws vs. other fasteners, and that is due to their superior strength and advanced design.
