Doesn't show the hex head, but it'll just be a different set of dies.
Dice? Dunno.

Cheers. I enjoyed that video. Those automatic machines are impressive.

I liked the thread forming best, I was expecting some sort of 'normal'
rotating die.

Cheers

I am pretty sure that rolling threads is both faster and results in a
stronger bolt or screw.
