    I have looked, asked n surfed for the thread size on a dual terminal Numax xv31mf leisure battery but no one seems to know or won't let on?
    I think it is American imperial thread but need a couple of wing nuts to fit.
    Anyone here got a clue pleeeaazze.....:cry:

    hi you could always pop along to a local engineers workshop they sometimes have a gauge that tells what it is or failing that they may be able to re-thread the studs to something more common.
    from memory its quite a coarse thread.

    Hi.
    If it's a coarse thread it will be a UNC thread. Just measure the outside dia to get the size which will be fractional, from memory 5/16".

    Cheers Mike.

    Odds on 5/16th UNC and quite possibly, so worth checking, the neg will be 5/16th and the positive 3/8th UNC, nowt simple eh?

    I suspect they are actually 5/16 whitworth so if a bit too loose or too tight try a Whit nut. Same number of teeth per inch just a different thread angle.
