Star Nut Setter

Set a star-fangled nut in your fork's 1 or 1-1/8-inch threadless steerer tube with the Star Nut Setter from Unior. Perfect for the do-it-yourself home mechanic, it's designed to install the nut into its new home at a specific depth. We'd recommend pairing it with the threadless setting guide to ensure the nut is driven in straight and to help reduce banged up fingers and pinched skin. Simply thread the nut on the setter and with your trusty hammer, drive the nut inside the steerer until the tool bottoms out. Crafted of tool grade steel, this is a tool that you only purchase once.
