    Could someone please explain or give us a link to a site that explains thread numbers? I grew up with Imperial threads but that was 30 years ago. Adaware asked the question but the answer by stevehuckss396 just gives the metric equivalent but doesn’t really explain it (no criticism meant). I’ve just spent nearly an hour looking for the answer but with no luck. I googled it but it seems that computing and internet threads take precedence over physical threads.
    I realise the last number is the threads per inch but what do the first numbers mean? (eg: #8 or #10) Is it like gauge numbers where the smaller the number the bigger the size? I looked at gauge numbers but they don’t seem to line up with “#10 = 4.82mm” so I really don’t have a clue.... Does this relate to all (american) threads or only Spark plug threads? I even checked out NGK's web site but found no help.
    thanks in advance.

    A number zero screw has a shank diameter of 0.060"

    Each screw number larger increases the shank diameter by 0.013", up through #12. After #6, there are generally no odd numbers.

    Thanks guys! This place is awesome for the body of knowledge of its members. The bit of info I was missing can be summarized by:

    The thread numbering system is a system that fills the gap for all imperial (inch) threads under the 1/4" size. #12 being the first size under 1/4" and #0 (probably) being the smallest on offer. The second number being the TPI and the first number being just an assigned number with (as Tom said) each screw number larger increases the shank diameter by 0.013", up through #12. After #6, there are generally no odd numbers.
    Once again, thanks guys!

    Well My plans are complete and I have started to build it. Will take months but will be a fun journey. If all goes well, I will make the plans available in some form or another.

    Another fine looking machine in the making!

    Looks large, or is the table small?

    Red to red and black to black, or it's ashes to ashes and dust to dust.
