    I'm about to embark on my first serious mod, inspired by the genius I've seen on these forums :clap: . One thing I've learnt is the importance of preparation :naughty:

    SO I 'm trying to find out what the bolts sizes are that are used in contructing a PC e.g standard case bolt sizes, hard drive mounting etc. I have :search: but to no avail. Can anyone help me here :blush:
    Thanks

    I have never seen anything but 6-32 and M3. All my CD/DVD-ROM and floppy drives use M3. All my hard drives use 6-32. Maximum allowed penetration of the screws into the hole is usually 0.15" (3.8mm) max., sometimes 0.25in (6mm). Minimum required penetration seems to be 0.125" (3.2mm), but that's just a guess.

    Seagate has drawings for HD in their documentation for download and Sony has drawings for CDs. The best documentation I found for a floppy was from YE-Data (never heard about them before), google for FDAA-520037 to find the document.

    The studs for mounting the motherboard must stick out 0.088" (2.235mm) above the lower edge of the ATX-I/O cutout and have at most 0.4" (10mm) diameter (ATX Rev. 2.1.). They can either be M3 or 6-32.

    6-32 is the US equivalent of M3. It is a #6 wire gauge diameter screw with 32 turns per inch. Confused :confused: ? Don't, worry :worried: you are not alone. For larger screws (then called bolts) the diameter is given in fractional inches, such as 1/4-20 for 0.25 inch diameter with 20 turns per inch. Check link for exact dimensions.

    I used 6-32 through-out my case, but found that the CDR, DVD and HD mount holes were some size slightly smaller...no problem I just tapped them out. Bottom line, the mounting screws for HD's and such may be a smaller size than 6-32.
