What type of screws is used in VGA connectors ?

Here's a very simple one.

I need to build some weird adapter for a PC's VGA (15 pin, 3 row D-SUB / DE15 / HD15) port, and I want to buy a case for it with the correct screw type.
Wherever I read about that plug type, two types of screws are mentioned:

  • M3 (metric)
  • UNC 4-40

Any hint (link to some official spec sheet, etc.) what screw type is standard for the VGA port ?

M3 describes the inner and outer thread diameters but go with UNC 4-40 which is both the diameter and pitch
UNC 4-40 female heads for the sockets, thumb screws for the plugs.  The standard screw length on plugs is 47mm
but if you're building your own device they are easily cut to length.

According to this: https://en.wikipedia.org/wiki/Computer_case_screws they are 4-40.  M3 screws are metric and are often used on other parts of the computer and are different pitch and diameter.
