Sometimes simple tools are the best ones to make, they aren't complicated but small tweaks to the smallest of details can stack up to big improvements in function. The Star Nut Setter is one of those tools. A simple task to install the star nut into a metal fork steer tube so you can preload your threadless headset. The outer guide slips over the steer tube and make sure that the driver stays straight while you hammer the nut into the steer. The driver has a hard stop to give you a perfect install depth as well. We took the extra clearance out of the two pieces of this tool to refine this design to something worthy of Abbey Green.
