Blue Chip Rescue Grub Screw for FCS and Future fin boxes:
  • FCS and Future fin boxes are great but the retaining grub screws can, if over tightened, strip the thread of the composite material they are located in. this can be a frustrating experience and often results in the complete finbox having to be replaced and that is time consuming and expensive.
  • Blue Chip now supplies a Rescue Grub Screw that will save you time, frustration and expense.
  • We have the Rescue Grub Screw made with a fine high grip 80° thread pitch and is 0.225 mm wider than the original grub screws supplied with your board.
  • The Rescue Grub Screw has a higher grip surface than your original grub screw
  • The Rescue Grub Screw will cut its own new and secure thread into your original stripped grub screw placement in your board and operate as normal.
  • Remember, do not over tighten your grub screws, they only need to pinch the fin lug.

How to fit a US Box fin

  

 

Installing the fin (US box systems)
Insert the brass plate into the fin box slot and slide it completely forwards.

Insert the fin into the fin box slot and slide backwards to the desired position. By default, the recommended position is either marked on the board or it is centred in the box. Adjusting the fin position forwards or backwards will depend on personal preference and tuning.

Rotate the fin until the fin sits almost flush with the board's bottom surface Align the brass plate hole to the one in the fin base head, insert the fin bolt through the holes and tighten securely until the fin base is flush with the board's bottom surface.
