What crimp for 10mm fly lead to earthing nut ?

[davesparks]

Keep the earthing nuts for small stuff up to 4mm cable.

Why? I use earthing nuts for all sizes of SWA gland and haven't had an issue.
They are a lot better in the 32mm and upwards sizes as they have an M8 stud instead of the little screws.

Well an M4 screw itself can't carry much current compared to 10mm cable, nor can it apply a lot of clamping force to make sure something that stiff stays in place, etc.

The screw shouldn't be expected current, it should only be clamping the lug to the brass.

Likewise the terminal screw shouldn't be making sure something stiff stays in place, the regulations require that terminations are not placed under any undue stress. Conductors should be formed (and supported if required) such that the termination isn't under stress.

I'd only seen them up to 32mm as that's the largest I'd ever sourced. Recently I learned they're available up to 75mm and that their price is suitably frightening. Then again 300mm 4 core isn't exactly cheap, so cost pales somewhat in that regard.
