Easiest way with female threads is just to test fit a known male thread. I'd be surprised if mudguard eyes were bigger than M6, M5 is the most common size but M6 is sometimes seen. Screwing Ti into Ti has more potential for galling, but whatever you use you need to lubricate the threads with Copaslip or similar.
Thanks - I think the front are m6, Maybe? I know the ones on the back are bigger still since they need to take the guards and the rack.
I'll maybe pop down the shop at lunch and see if I can get 1 of each then get home and order them on line.
