Hi

The end plate studs are 1 mm pitch (M7 x 1.0) & the original studs were strong (or tough), as they had rolled threads rather than cut threads.

They are exactly the same pitch as 'normal' M6 threads but 1 mm bigger in diameter & correspondingly stronger with their bigger cross section.

I hope that helps.
