    OK, tell me if I'm losing my mind.

    So I need and cant find a 5/16 socket. Go to the hardware store, buy 5/16 socket, socket is too big for 5/16 hex head machine screw. 5/16 wrench fits perfect so I know it's 5/16. Go back to hardware store with screw. None of the standard 5/16 sockets fit. But the 5/16 deep socket fits.

    So I tell the old guy who works there "Hey, these things must be mismarked or something because they don't fit." He says, "No, the 5/16 socket is a 12 point socket and that is a different size than the six point deep socket"

    Now I figure the guy that's worked 50 years in the hardware store probably has forgotten more about hardware and tools than I'll ever know, but how the hell is a socket any bigger or smaller based on the number of points? Why isn't 5/16 of an inch 5/16 or an inch no matter what?

    Not really the size maybe. It would be like looking at the same size of allen wrench and star wrench. You could fit the allen wrench in the star wrench hole but could not fit the star wrench in the allen wrench hole. Just a thought.

    The sizes should be the same. The problem is that your hex head screw is probably metric and slightly smaller than 5/16.

    And star (Torx) wrenches are neither metric nor SAE AFAIK.

    The hex head screw probably has a low tolerance and is slightly smaller than 5/16", and 12 point sockets don't ever fit as well as 6 pointers, because there is less mating surface.

    It can also be crappy quality control at the either the spanner or bolt factory.
    I have a few spanners and sockets of the same size and I quite often find that some wont fit the same hexagonal

    if itts torx, don forgert about the other option. like torx puls.
    5/16 is like 8mm or 7mm.

    use vise gips.

    Go back and ask him for a round wrench, tell him you have a bolt head that is round and you are looking for the round wrench.

    In cheapo socket sets, I have found that 5/16ths is often not right.....but I have no explanation. Really. Evidently there is no Tiwanese translation for "five-sixteenths"

    I am not making this up, no s***.....really.

    Your first problem was going to a hardware store for anything more than twine. I think your hardware store hired an old timer to give the impression that he knew something when in fact all it proves is most common folk that go to hardware stores these days know even less than the guy who is trying to supplement his pathetic social security income.


    Oh, by the way.
    RT,

    There you go throwing quality aviation hardware at an True Value problem. (dam smilies don't f'in work)

    Hardware stores are all selling remarked made in China/Taiwan/whatever tools. Save money by getting them from harbor freight if hardware store tools are good enough for you.

    Anyone notice your feet getting bigger? I mean if you used to always wear size ten boots you now wear size ten, eleven, twelve, even thirteen depending on the maker name but your feet look the same? They don't do sizes very good in anything.
