I have a four wheeler and a bolt has...

Use vice grips if you have access to it, if not, go to the local hardware store and get a set of easy outs, they will come in handy. drill a pilot hole in the bolt, then use the easy out.Best of Luck!

You can use an "easy out". You drill in to the head of the bolt and use the tool that loosens as you tighten. You can get them at auto parts stores

[mr2mike89]

not much else to say but use the easy out, if that doesnt work youll have to drill out the bolt and rethread the hole

[eldoradodave]

weld another bolt to the top of it. Then you can use a wrench to back it out. Done this on quite a bit of machinery over the years and cars

[strech]

First, if accessable, use vise grips.If not, you can try an easi-out.Or, grind flats in the side so you can use a wrench.Or cut a slot in the head for a screwdriver.
