FBC Locking Foil Track Nuts M6 & M8 | Foil Mounting Hardware

The FBC Locking Foil Track Nuts M6 & M8 are designed for foilers who want a quicker, cleaner and more reliable way to mount their foil. Instead of dealing with track nuts that slide around inside the box while you line everything up, these locking nuts stay exactly where you want them. That means less fumbling on the beach, less frustration in the wind, and a much easier setup every time.

Made in the EU from precision CNC-machined marine-grade brass, they are built for strength, corrosion resistance and long-term durability in saltwater use. Each nut uses A4 marine-grade stainless-steel grub screws to lock firmly into position inside the foil track, helping you install your foil with more control and accuracy.

For riders who regularly take their foil on and off, travel with gear, or simply want to make setup faster, this is one of those small upgrades that makes a noticeable difference.

Real-World Use

In real use, these make foil setup feel much less awkward. Standard track nuts can shift around just as you are trying to line up your plate, which is frustrating at the best of times and even worse when you are rigging in wind or balancing the board on the beach. These locking nuts remove most of that hassle.

Once set in position, they stay where you need them, so fitting your foil becomes a much more controlled job. It is a simple bit of hardware, but for many riders it is the kind of upgrade that quickly becomes part of the setup they would not want to go without.
