A 4-piece nut splitter set is used to cut and remove rusted, damaged, or corroded nuts without damaging the underlying bolt threads. The set is ideal for home, workshop, or hobbyist use and consists of four different sizes to tackle a wide range of nuts. Each splitter works by being placed over a nut and then tightened with a wrench, causing a sharp blade to cut through the nut and split it open for easy removal.
