FBC – Locking Foil Track Nuts M6 & M8 – Product Description

The FBC Locking Foil Track Nuts (M6 & M8) are engineered to make mounting your foil quicker, easier and far more secure. Instead of fighting with hardware that slides back and forth inside the track, these precision-made locking nuts hold their position so you can simply bolt and go — even in windy or sandy conditions.

Manufactured in the EU from premium marine-grade brass on a precision CNC machine, these nuts deliver exceptional strength, corrosion resistance and long-lasting reliability. Each nut features an integrated locking system using marine A4 stainless-steel grub screws, allowing you to fix the nut in place before aligning your foil plate. This eliminates frustration, speeds up your setup, and provides a more controlled and accurate foil mounting process.

Whether you’re wingfoiling, SUP foiling, kite foiling or prone foiling, these locking nuts offer the smoothest, most dependable hardware experience. Built for riders who demand convenience and durability, they’re one of the simplest yet most valuable upgrades you can make to your foil setup.
