Installing front wheel, what size hex?

Hi guys, I'm re-installing my front wheel and I noticed I don't have a hex socket big enough to fit into the hole so I can tighten up the axle nut first. Plan on going out to Harbor Freight tomorrow, looks like they have a 1/2in set that has 17mm as the largest size. Would this happen to be the size I need?

I know I can tighten the pinch bolts on the right side first "in a pinch" but since I'm going to be changing wheels a bunch, i figure I'd have the right tools to do it correctly, ie:

1) Tighten axle nut to spec
2) Tigthen left side pinch bolts to spec
3) Make sure right side fork will move freely
4) Compress the front shocks a few times
5) Tighten right side pinch bolts

Seem right to y'all? Thanks much!

Sounds good.

14mm. But I've never found I needed one. Another alternative is the Motion Pro 5/8" thin-wall spark plug socket and extension. The back end of the socket is milled to 19mm (which I used to use on the front wheel of my F800GS), and the back end of the extension is likewise milled to 14mm.
