Stromberg enricher shaft thread size

When I was taking everything apart a few weeks ago, the nut on this shaft was apparently very loose and it fell off and promptly went through a dimensional portal to bugger knows where.

Nothing amongst the numerous loose nuts in my bins of random fasteners fits it. Does anybody know the thread size?

Will try to remember to search my carb part box tomorrow morning and get back to you.

I measured it with my tap and die set as an m7x1

Thanks Henry, that sounds plausible. For a little while there I was beginning to wonder if it was one of those ‘unabomber’ fasteners! :mrgreen:
