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.

Hi Trev,

I ran a 6mm die down the threads and used SS dome nuts

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?
