To make a long story short, What is the opinion on welding a bolt head in place so it can not be removed with out some work. I wasn't going to weld continuous around it, just spot it on the wrench surfaces. Will the heat have any real effect on the bolt strength? Warn only supplied 5/16 bolts to begin with so I'm a little concerned about weakening cause' there not a whole lot of room for a larger bolt. Some one tried to steal my winch , now I'll make it really difficult to remove, although it wasn't easy before, thats why it's still there.
