Can somebody please advise what thread size are the fixing studs on the Smiths Chrono Speedo and Rev-counter?

Sorry John, but they are 6mm x 1.0mm.
All Chrono threads are metric.
0 BA is also metric and will fit but the angle is different, being 47 degrees instead of 60.

Thanks for the replies.

Tried an OBA nut which screwed on but was very loose. Tried a M6 nut which screwed on perfectly.

I have some dome nuts, they will look nice?
