636 front axle size

I went to change the tire on a 636 tonight and didn't have a hex key big enough for the front axle. Could someone please tell me what size it is so I can order one. Or better yet, tell me a better way to get it out. TIA.

Or mess around looking for something else to put in the axle, and then use a wrench on whatever you find.

 

That is awesome. I will order one right now. Thanks.
