if the threads are just slightly misshaped, than you might be able to run a grade 8 nut over the threads, this will straighten them out well enough to use in most applications. (make sure the nut starts the threading straight or you will crossthread the bolt and it will likely be junk) if the threads are severly damaged you will need to buy a "die" and run the die over the bolt. a die looks like a large nut but instead of having smooth threads on the inside they have cutting edges. these can be bought at any hardware store, and they can be kind of pricy. ---- unless this is a special bolt that you cannot find anywhere to replace it with or it is expensive to replace, i would recomend just buying a new one.
