Gunfight IV and STECS Mounting Holes?

[Torbinator]

Hello,

Hello, I purchased the Standard STECS. Can somebody tell me what size screw and countersunk head angle I should use for STECS' four corner-holes so I can mount it to a desk?

Also, I plan to buy longer screws that will allow me to attach the Gunfighter base to the same surface as STECS. Can somebody tell me the size of the screw and thread that the
Gunfighter base uses?

I did watch some VKB videos but there was nothing specific enough to give me an answer to the questions above.

Thank you..
