We have all experienced the frustration of being held up by one stubbornly seized nut that just refuses to move. Penetrating oil, wire brushes, even heat will not budge it. In order to remove such corroded or damaged nuts, without damaging the thread on the often more important bolt or stud, the last resort is the Nut Splitter. The hardened steel cutting tip is driven into the side so that it drops off. Hopefully you won’t need it often, but when you do you’ll be glad you have it.
