Wheel hub/bearing Mounting bolts 99 yukon 4wd

[gmdrvr]

I need some hub mounting bolts for a 99 4x4 yukon. I got the dimensions for the bolts I need and I went to the hardware store, the guy showed me a bolt that size but the bolt he showed me was a 22mm socket size and I think I need a 14 or 15 mm with a flange. He also asked what thread length I need but that I didn't know. Do the threads for the mounting bolts go all the way to the head? Does anyone have a picture of these bolts?
