Park Tool TNS-4 Deluxe Threadless Star Nut Setting Tool - 1 1-8th Inch

If you have purchased a new fork and need to install a new star-fangled nut, make sure you install it correctly the first time. Sure you could bang it in with a screwdriver and hammer, but you risk damaging your expensive steerer tube or may end up with a misaligned star nut. Get perfect alignment and depth with the Park Tool TNS-4 Deluxe Threadless Star Nut setting tool.

Who's this item for: Professional or home mechanics who need a tool to precisely install star-fangled nuts into steerer tubes that use a 1" or 1-1/8" threadless headset system.

Compatibility: Compatible with star-fangled nuts that use an M6 thread only. Not compatible with M10 threaded nuts.

Pros: Will get your star-fangled nut perfectly aligned and at the correct depth with no pinched fingers.
