Foilite Titanium Hydrofoil Track Lock Universal Track Nut Set of 4

The Foilite Titanium Hydrofoil Track Lock Universal Track Nut Set of 4 is a precision-machined hardware kit distributed by PKS and designed for mounting hydrofoils to track-based board systems. Each set includes four CNC-machined Grade 5 (GR5) titanium T-nuts along with matching titanium set screws in both M6 and M8 sizes. The defining feature of these track nuts is a built-in locking mechanism: a set screw threads into one side of the nut to fix it in position within the board's track, preventing the nut from sliding or spinning during assembly or on the water.

The dual-thread design makes these nuts compatible with foil systems that use either M6 or M8 mounting hardware. Each nut has both an M6 and an M8 threaded hole. When mounting an M6 foil, the rider uses the included M8 set screw to lock the nut in the track, leaving the M6 hole open for the foil's mounting bolt — and vice versa for M8 setups.

• Material: 100% Grade 5 (GR5) Titanium
• Manufacturing: Precision CNC machined
• Thread compatibility: M6 and M8
• Included: 4 titanium T-nuts, 4 titanium M6 set screws, 4 titanium M8 set screws
• Track type: Universal (fits standard foil board tracks)

These track nuts suit any rider running a track-mount foil board — from wingfoilers and prone foilers to kitefoilers — who wants a durable, corrosion-resistant upgrade over standard stainless-steel or aluminum hardware. Because the locking set screw holds the nut firmly in place, setup and stance adjustments on the beach become faster and less frustrating; riders no longer need to hold the nut from the bottom of the track or worry about it shifting while threading bolts.

The universal M6/M8 design is particularly useful for riders who switch between foil brands or own multiple foils with different bolt patterns. Rather than keeping separate hardware kits, one set of these nuts covers both standards. The titanium construction also appeals to riders in saltwater environments who have dealt with corroded steel nuts seizing in their tracks.

PKS distributes a range of Foilite-branded titanium foil hardware, and these track nuts sit alongside titanium foil mounting bolts and other corrosion-resistant accessories in that lineup. Compared to standard stainless-steel track nuts — often included free with foil boards — the Foilite set is a purpose-built upgrade that adds the locking feature and swaps to a lighter, more corrosion-resistant material. Within the broader market, Slingshot and other brands offer their own titanium or stainless track nuts, but the dual M6/M8 universal threading and integrated lock screw distinguish the Foilite design. For riders already invested in track-mount boards, this is a straightforward hardware swap that requires no modification to the board or foil base plate.
