D104 Bottom Plate Screw Size ??

[Wire Weasel]

Hi guys, wondering if anyone here as identified the Screw Size in the past on D104 bottom plates. It is a 3 mm flat head machine screw .... but apparently it is an oddball thread count pattern. Anyone know what the screw size is?

I have tried the local large hardware store. Their thread gauge did not cover this screw.

I have searched the web for mechanical specs on the D104's but all I find is electronic specs and overall mic. dimensions etc .... but no complete mechanical spec drawings.

Any help ? Thanks !!

Sometimes it's just easier to break out the tap and die set and make a new set of threads that match something more common like 6-32 or even 8-32.
