Park Tool Threadless Star Nut Setter

Park's Threadless Star Nut Setter makes it quick and easy to install the star-fangled nuts used with 1-1/4- and 1-1/2-inch threadless headset systems. With its durable steel driver, this precision tool holds the star nut securely and you strike the tool's end with a hammer to set the star nut to the perfect depth inside the steerer, every time.
