    it might be 1/4 npt, that is about 1/2" and 18 tpi. im sure i have 1/4 npt taps in the workshop, i will have a look in the morning, could pop one in the post for you to borrow (cheaper than buying one just for one hole). all it will cost is the postage and a donation to charity.

    Hi V8Ian,

    1/4 NPT makes sense as my bolt size measurer would only go half way up the thread in the 1/2" hole. It's an American throttle cable with a threaded bolt attached. How do you tap out a tapered thread or is the tap the same diameter through it's whole length?

    Thanks.

    im fairly sure 1/4 NPT is 1/2"od x 18tpi, it may also be a UK conduit thread? ll have a look tomorrow and see if I have a tap

    What's it off. UK or US?

    Just had a look through my bible, and it's none of the usual ones.
    Any chance you could drill and cut a new thread such as M14?
