Park Tool - TNS - Threadless Nut Setters

Frame & Fork Tools

Product Details



The TNS-1 is used to install the star-fangled nut found on 1” and 1-1/8” 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 and keeps it straight. Long handle helps prevent pinched fingers.

The TNS-4 makes it quick and easy to install star-fangled nuts used with 1" and 1-1/8" threadless headset systems. Using a durable steel driver and built-in guide, the TNS-4 perfectly aligns the star-fangled nut and sets it to the proper depth every time. The unique design virtually eliminates pinched fingers. Replaceable set screw (#822).
