Urgent. Doing Tranny filter change on ZF5HP18

[Alpinewhite]

The fill hole on this tranny has a huge Allen bolt. Where do I get so huge a Allen socket or key. what do you guys use. What is the dimension (mm) of this thing.

I am in my friends house and my car is on stands. I got to complete this job by 9PM EST for various other reasons.

Thanks
Arun
