The TNS-4 Star Nut Setter easily fits 1" and 1-1/8" forks. With a precision machined sleeve and a comfortable grip, the Threadless Nut Setter is used to install the star-fangled nut found on AheadSet® and other threadless headset systems. Thread the nut onto the TNS, insert into the fork stack, and tap it in with a hammer. Sets the star-fangled nut to 15mm into the steer tube and keeps it straight for proper threading.
This was my first time to cut, prepare, and install a new fork. I was worried about this part of the install, but this tool took all the guess work out of it. The star nut screws on to the bottom, whack the tool until the plunger can't go anymore...unscrew it, and you're done. I re-checked several times, and compared it to a lot of other forks, and every time I can tell that mine is perfectly set. Quality tool to take the guess work out of this hairy install.
Why didn't I get this a long time ago! ??????? I've always finagled the star nut in with a bolt hammer n screwdriver which would take quite a few mins. . This tool makes installation a piece of cake. Wam bam thank you ma'am!!
I really don't know why I waited so long to buy one of these. I had always just used a socket or another tool and for the most part it would work. But this last time I screwed it up on my 40 and I told my self that I would invest in one and I am glad that I did. Makes it so simple 2 hits with the hammer and it is done!!
