Grub screw hole size for threading!

[gingea1pom]

Cheers men,

Thanks TT, obviously I could have done that myself but didn’t so other forum members would benefit.

I know it is probably imposable to see from the picture and I should really give them a bell in the morning but does the grub screw in the picture look course or fine.

I am hoping course as it can only be one hole size opposed to the three hole sizes for different pitches of fine thread.
