PKS Foilite Titanium Track Lock Universal Track Nut- 4 Pack

The PKS Foilite Titanium Track Lock Universal Track Nut is a set of four CNC-machined track nuts built from Grade 5 (GR5) titanium, designed to secure a hydrofoil to any board equipped with a standard track mount. Distributed by PKS under the Foilite hardware line, these track nuts address two common frustrations with conventional track hardware: corrosion from saltwater exposure and unwanted nut movement inside the track during assembly or adjustment. Each nut features a built-in set-screw hole that lets riders lock it at a fixed position along the track, eliminating the need to hold the nut in place while threading bolts from below.

• Material: 100% Grade 5 (GR5) Titanium
• Manufacturing: Precision CNC machined
• Thread compatibility: M6 and M8 (dual-threaded screw holes)
• Locking mechanism: Set screw (both M6 and M8 set screws included)
• Pack contents: 4 titanium track T-nuts, 4 titanium M6 set screws, 4 titanium M8 set screws

These track nuts suit any wing foiler, kite foiler, or prone foiler who mounts a hydrofoil via a standard track system and wants hardware that holds up in salt water without seizing, corroding, or adding unnecessary weight. Riders who frequently adjust their foil position along the track — whether to fine-tune balance, experiment with mast placement, or swap between foil setups — will benefit from the locking set-screw design, which keeps the nuts stationary during changes.

Because the nuts accept both M6 and M8 bolts, they work across a wide range of foil brands and board track systems without requiring separate hardware sets. That universal fit makes them a practical choice for riders running gear from multiple manufacturers or transitioning between setups.

The Foilite line from PKS focuses on titanium hydrofoil mounting hardware, and the Track Lock Universal Track Nut sits alongside other Foilite fasteners such as titanium foil mounting bolts and washers. Within that line, the track nut is the primary product for track-based foil attachment, as opposed to the bolt sets aimed at tuttle-box or plate-mount configurations.

Compared to stainless-steel track nuts from brands like Slingshot or generic aftermarket options, the Foilite titanium version is positioned as a premium upgrade. GR5 titanium offers a meaningful weight reduction — roughly half the weight of steel at comparable strength — and significantly better resistance to pitting and crevice corrosion in marine environments. For riders who have dealt with seized or corroded stainless hardware after a season of saltwater use, the price premium over steel nuts reflects longer service life and easier maintenance.
