I think the donut is just for setting the depth.

Most of the bolt holes on the m62 I've worked on were much bigger than 6mm so I would not have a problem either using helicoil or tapping to a bigger size. Like mentioned I've used 5/16 in place of 1/4 in S.A.E. that would mean 8mm in metric.

10 Nm on an m8-1.0 will get you just about identical clamping force
