Steering Shaft Nut Size?

Good Morning Everybody!

I was on the trail yesterday, and about a hundred yards before the end of the trail, I lost control of my 2004 Honda Rancher 350 4WD. It rolled onto it’s side, and when I flipped it back over the front wheels were pointing opposite ways. The nut on the steering shaft that holds the tire rod plate onto the shaft came off. I guess that’s what caused the quad to go out of control.

My question is this: What thread size is that nut? Can I just put a new nut and a cotter pin in it and expect it to fix it?

Thanks!
