  • Screw Size for NVMe

    From Jeff Gaines@21:1/5 to All on Tue Feb 27 10:27:40 2024
    In my computer shuffling I have discovered the NVMe on the Z170K is loose
    and slips out of the screw. It needs a very fine thread but a big head (or washer I suppose).

    Can anybody confirm the thread size please? It is smaller than the very
    fine threaded SSD screws (are they screws or bolts nowadays?).

    As far as I can see it is M2 or is that too logical?

    I was standing in the park wondering why Frisbees got bigger as they get closer.
    Then it hit me.

    Best I can tell under a loupe, it's M2 with a 0.5mm pitch.

    Thanks Andy. I have size 12 feet and hands to match so this size is really bogging awkward for me :-)

    You know it's cold outside when you go outside and it's cold.

    I wouldnt count on it - the screws which hold "normal" drives in place
    are a UNC thread I believe.

    And the jackscrews on D type connectors are definitely 4-40 UNC

    So far I have found coarse screws which are for PSU, cases and 3.5" HD.
    6-32 UNC
    Fine threaded for SSDs. M3
    These awkward little sods for NVMe which I wouldn't be surprised are
    different sizes depending on the day of the week! Why didn't they stick to
    the fine screws (M3) I really don't know.

    Anyway I have ordered some and will have to see if they fit.

    I also have a small piece of an M3 stuck in a drive cage with a small
    sharp point bit (0.5 mm but enough to cut you) on the outside and perhaps
    2 mm on the inside. Still racking brain on that one, much to small to
    centre punch and the cage contains electronics so grinding may not be a
    good idea.

    I've been through the desert on a horse with no name.
    It was a right bugger to get him back when he ran off.

    one of my NVMe enclosures uses little rubber "pegs" rather than screws.

    I bought a pack of these things on eBay a few months back, and what you
    are suggesting is correct - its a small (M2 ?) screw with a big head,
    and there are no washers involved.

    There were some of the standoff (screw / nut) things in the pack with it.

    That's encouraging, thanks :-)

    How does a gender neutral bog differ from a unisex bog ?
    It has a non-binary number on the door.

    crucial seem to say that M2x0.4 rather than 0.5 that I gauged under my
    loupe is a common size

    <https://www.crucial.com/support/articles-faq-ssd/about-m2-ssd-screws>

    "M2 screw sizes are not standardised" - why not, all the other screw sizes
    on cases and drives are. I must admit I didn't fit an NVMe straight away
    when I got the Z170K but I sure as heck can't find a screw or stand off now!

    My kits arrived from Amazon. Nice assortment of stand-offs and screws (why aren't they called bolts?) and the first one of the packages fitted
    perfectly.

    Thanks for all the input :-)

    (why aren't they called bolts?)

    They are called screws (or setscrews) because there is a thread for the
    entire length of the shank - regardless of the type of head.

    A bolt only needs to have enough thread on it to hold a nut at the end
    (also regardless of head style)

    Also remember ...

    Wood "screws" have no part in this discussion, and ...

    The bolt on my front door has no thread at all

    The fact that there's a highway to hell and only a stairway to heaven says
    a lot about anticipated traffic numbers.
