Fortitude Humbucker poles

[Bowtomecha]

I just found out that the dimarzio fortitude has oversized screw poles. I’m wondering if they are in fact bobbins meant for dimarzios with the wider Allen poles and they managed using larger diameter screws. Has anybody tried this on their dimarzios and what size were the screw poles if you did?

What thread is that? Looks even bigger than the 6-40 screws used in Gretsch Filter'Trons.

Those look like the same size used in the Wide-Range humbucker. But I don't know the exact thread size.
