This impact tool ensures that an Ahead star nut is inserted accurately into the steerer tube at a predefined depth.
For inserting 1" and 1 1/8" star nuts:
- 1) Hand-tighten the required bushing (1" or 1 1/8") into the impact tool.
- 2) Using the circular cross hole, screw the star nut to be installed onto the central spindle until it stops against the grub screw.
- 3) Place the tool on top of the steerer tube and tap it down with a hammer until it stops.
- 4) Remove the impact tool from the steerer tube by turning the knurled screw to the left (anticlockwise). The star nut will remain in place in the steerer tube.
