DELUXE THREADLESS NUT SETTER
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).
Fits star-fangled nuts with an M6 threaded nut. Not compatible with M10 threaded star-fangled nuts.
