Hexagon head cap screws have a hexagon shaped bolt head for tightening with a wrench or socket tool, and a circular bearing surface under the head, known as a washer face. These screws can be full thread or partial thread, with some shorter lengths only available as full thread and some longer lengths only available as partial thread. The thread length of partial thread hex head cap screws depends on the diameter of the screw. The size of the head depends on the diameter of the screw as well. Threading can be coarse or fine. The main metric hex head cap screws are DIN 933, DIN 931, ISO 4014, and ISO 4017. See more about the difference between the DIN and ISO hex head cap screws here.
