Product Details

The Park Tool TNS-1 Star Nut Setter is designed for the precise installation of star-fangled nuts in threadless headset systems. This tool is essential for ensuring a secure fit of the star-fangled nut in the steerer tube of your bike, a crucial step for setting up threadless headsets.

The process is simple: thread the star-fangled nut onto the TNS-1, insert it into the steerer tube, and tap it in with a hammer. The TNS-1 sets the nut to the recommended 15mm depth while ensuring it remains perfectly straight during installation. The long handle adds comfort and helps prevent pinched fingers, making the job safer and more efficient.

Key Features:

  • Precise Installation – Installs star-fangled nuts to the recommended 15mm depth for threadless headset systems.
  • Easy-to-Use – Thread the star nut onto the tool and tap it in with a hammer for a secure fit.
  • Straightforward Design – Keeps the star-fangled nut straight during installation to avoid misalignment.
  • Long Handle – Offers added leverage and comfort, while preventing pinched fingers during use.
