Park Tool TNS-4 Deluxe Threadless Nut SetterAchieve workshop-level precision and safety with the Park Tool TNS-4 Deluxe Threadless Nut Setter, the essential tool for flawless headset maintenance. Installing a star-fangled nut can be one of the most frustrating and risky steps in servicing a threadless headset system. A misaligned or incorrectly set nut can lead to improper headset preload, potential damage to your fork´s steerer tube, and a compromised front end. The TNS-4 is expertly engineered to eliminate these issues, providing perfect results for both professional mechanics and dedicated home enthusiasts.The TNS-4 makes it quick and easy to install star-fangled nuts used with 1´´ and 1-1/8´´ threadless headset systems. Its ingenious design is centered around a long, heavy-duty driver and a built-in guide sleeve that work in harmony to ensure absolute accuracy. This system perfectly aligns the star-fangled nut with the steerer tube and sets it to the proper depth every time, removing all guesswork from the process. This consistent depth is critical for allowing your top cap and compression bolt to apply the correct preload on the headset bearings, ensuring smooth, reliable steering.One of the standout benefits of the TNS-4 is its commitment to user safety. The unique design with its outer sleeve guide virtually eliminates the risk of painful pinched fingers, a common hazard when using makeshift installation methods. You can confidently strike the driver handle without worrying about your hands being near the point of impact. This focus on safety and simplicity makes a potentially difficult job straightforward and secure.Built for the rigors of a busy workshop, this deluxe nut setter is a long-term investment in your tool collection.
