Is there a standard screw size for the mounting holes of PC fans? Specifically, 92 mm x 25 mm.

I ask because I'm having an acrylic lid custom made, including holes for long stainless steel screws to solidly mount the fan pointing downward.

I have 3 30mm fans ontop of my exo and they fit snug right into the eggcrate.
