Take the plug to a nut and bolt suppliers, they will tell you what it is.

Why not buy a few bolts local and try them with your finger over the hole?

The image suggests the Verniers are incorrectly positioned on the bolt. The knife edge section on the calipers is possibly measuring the thread root diameter. Try measuring with the flat part of the caliper faces, thus measuring the thread diameter.

Parts book has it as an M12x16 hex head sealed with an M12 Dowty washer. Thread pitch should be 1.75 since they haven't specified otherwise. The drain valve looks like it will use a Dowty washer to seal against the tank but impossible to say for sure from their photos.
