Nice work Don!

why not simply change the rear deck cap heads for hex heads?
Thank you! Great Question!
The smallest actual hex head bolts I can find are M3. The dimensions of an M3 hex head are 5.5mm across the flats and 6mm across the corners.
The holes in the plate are to accommodate the 5.5mm diameter of the M3 cap head screws and are just slightly larger.
For the fasteners to look correct in the plate, I would estimate that the holes would need to be at least 7.5mm across. Otherwise it wouldn't look like you could get a wrench on the bolt. The problem with that is as you can see in the picture several of the holes are very close to the edge of the plate as it is.
I played around with M3, M2.5 and M2 nuts to determine the aesthetic that looked best and would look the most "scale". To my eye the 4mm/4.3mm of the M2 looked the best with existing holes. At 1:6 scale the bolt would be approximately an inch which seemed like an OK size based on pictures of the real Jadgtiger. Also with the cap head screw still in place it looks like there's a washer under the nut.
These are the nylon nuts I got from Amazon to test with:

I took the dimensions of the nuts and add a "post" that will fit in the M3 socket heads. My buddy is ripping off a bunch on his 3D printer for me.
Definitely could have used M2.5 nuts and bolts mounted "upside down" with the bolts dremel'd down and the nuts "boltified" with some JB Weld, but again it looked a little cramped.
The "problem" now of course is that I'm probably going to modify the roof plate to use the same size fasteners. For that I may switch out the kit supplied M3 hex head bolts for M3 button head bolts and use my caps to provide the same "bolt w/ washer" aesthetic.
