Park Tool  CT-3 Screw Type Chain Tool

Because of the tremendous force needed to remove chain pins, our Screw Type Chain Tool is made from investment cast steel. Along with superior strength and durability, the CT-3 features a handy “loosening shelf” to remedy stiff links after reassembly. The fine thread and comfortable size enable easy removal of even the toughest chain pins. Like all Park Tool Chain Tools, it's easy to use and built to last.
