John,
It's true, as Christian says, that you don't have to model socket head cap screws if you don't want to; they're available in webspace. However, your question wasn't answered, and maybe you have good reason to create such a detailed model. (Frankly, most folks just sink a hex cut with a flat bottom, and don't worry about that conical surface which is created by a heading operation.) Anyway, here you go. Create a hex Surface going deeper than it will end up and a revolved conical surface going well beyond the hex. Now Merge the 2 Surfaces and Edit/Solidify to cut out the material. Good luck!

John,
No, the advantage of using intersecting (and crossing!) surfaces is that they can be completely independent of each other when individually created, then merged afterwards. In other words, the revolved conical suface goes beyond the hex extruded surface and vice versa.

Socket head cap screws are pressed.
But there is a way to dril square/hexagon holes even.

Modeling this is with a few steps first u cut conical inside material then u cut hexagonal hole with extrude from surface to circular surface of conical cut.You make sure your hex sketch is inscribed in conus. And then to complete hex conus transition you use same hex sketch but this time you add material outside of hex cut. kinda hard to put in words so here are few pics.
Your post is little bit confusing. Title ask how to model and in post u ask how its made.
