Default Sizes for Allen bolts on tranny?

Does anyone know what the size allen is for the drain plug on the tranny and the axle bolts? I dont have an allen socket/key big enough for the plug and the ones on the axle look crazy. Like some 12point allens that i've never seen before...

Drain and fill plugs are 17mm
Output shaft flanges use 8mm triple square (also known as cheesehead). These are different than 12 point hex.

The transaxle drain/fill plugs can be very tight. I had to weld a bolt with 17mm head onto a 3-ft long piece of angle iron to break one fill plug loose. Thanks to a tip on Clark's, I got the fill plug loose BEFORE draining the old fluid. (hint)

Make sure you loosen the fill plug before you drain it!

I spent something ridiculous on the snap-on 17MM hex driver...

yea thanks. i picked up the 17mm and a set of the triple square from the tool guy. like $15 for the 17mm and $60 for the triple square set...Also it helps to take the fill plug off before draining because it helps venting sorta like opening the breather when filling gas in your mower. Overall it went very well. All of the bolts came out relatively easily and the old seal wasnt too bad to get out. All i did was take 2 screws and drilled them in to pry it out. I took some pictures if anyone needs em for reference.
