RD350B rear axle nut size question

[rdsarefun]

I am on vacation and have the time to find some parts and pieces for my bike.  I searched the forum and found some answers, but not definitive.  I was wondering if anyone knew the socket size that fits the rear axle for a 350 (both the axle and the sprocket hub).  I want to buy a combo spanner wrench and am unsure of the exact size.

Thanks, Brian
