    Guys, as per title, I don't know where to find this info so this is the best place to ask, what thread (diameter and pitch) are the mounting screws for a power supply?

    Thanks.

    Based on this: https://en.wikipedia.org/wiki/Computer_case_screws#.236-32_UNC_screw

    The #6-32 UNC is a UTS screw specifying a major thread diameter of #6 which is defined as 0.1380 inches (3.51 mm); and 32 tpi (threads per inch) which equates to a thread pitch of 0.031250 inches (0.7938 mm). The optional UNC specification indicates the standard coarse thread is used which is defined for #6 screws as 32 tpi rendering 'UNC' redundant, however it may be seen when other specifications such as plating or other treatments are also specified. It is by far the most common screw found inside computer cases.[1] It commonly appears in lengths of 3/16 in (0.1875 inches (4.76 mm)) and 1/4 in (0.25 inches (6.4 mm)) or less often 5/16 in (0.3125 inches (7.94 mm)).

    I have and odd one that does use m3 so that might be a thing for you to keep in mind.

    Thanks mate, I tried M3 before I posted and it was a loose fit (hence my asking), so 6-32 makes sense since it's close to 3.5mm.
