    A machine screw has just dropped out of my best Shimano fishing reel and I am hoping I can determine the thread size and buy a few replacements.

    My best measurements are

    1.92mm MAX across the threads of the bolt.

    A 6mm/1/4 inch screw has 14 threads = 56 TPI

    Could it be M2

    If not what?

    Uploaded photo which you may be able to blow up.

    Thanks

    Mike

    Very difficult, that one Mike but the common USA thread is UNC @ 64 tpi, and gives a micrometer measurement of .0755".
    I think I'd be getting in touch with the manufacturer about this one!
    Good luck with it
    John :)

    Or just pop to a fishing shop that does repairs, they'll have one to hand surely.
