I don’t have time to demonstrate, but think of it in 2 main parts.

The head is a cone with 8 wedges cut out of it.

The screw shaft is a cylinder with threads revolved around it (search forum) AND the self tapping cuts are 3 triangles lofted and subtracted from the screw shaft… same principle as the threads.
