Foilite Foil Drive Titanium Mounting Bolts + Lock Nuts

The Foilite Foil Drive Titanium Mounting Bolts + Lock Nuts from PKS is a precision-machined hardware kit designed to simplify how riders attach a Foil Drive unit and hydrofoil assembly to their board. Sold as a set of four, the kit pairs Grade 5 titanium mounting studs with matching titanium cone nuts and includes an M3 hex key for installation. Available in M6 and M8 thread sizes, it covers the two most common hydrofoil track-mount standards. PKS markets the Foilite line specifically as a corrosion-proof, lightweight alternative to the steel fasteners that ship with most foil and Foil Drive packages.

• Material: Grade 5 (Ti-6Al-4V) titanium, CNC machined
• Thread sizes available: M6, M8
• Set contents: 4 mounting studs, 4 cone nuts, 1 M3 hex key
• Weight savings: Approximately 50% lighter than equivalent steel hardware
• Corrosion resistance: Saltwater-rated; resists pitting and microbiologically influenced corrosion

This kit targets riders running a Foil Drive electric-assist unit who want a single set of fasteners they can trust in salt water without routine replacement. Steel bolts in a marine environment are prone to galvanic corrosion and seizing, especially where dissimilar metals meet inside a foil track. Titanium eliminates that maintenance cycle, making the upgrade practical for anyone who rides regularly in the ocean rather than fresh water.

Because the hardware is compatible with standard M6 or M8 foil tracks, it suits a broad range of hydrofoil setups. Riders who frequently swap between boards or travel with their gear will appreciate the lighter weight and the included hex key, which keeps the install tool kit small. The product is most relevant to intermediate-through-advanced foilers who already own a Foil Drive system and are looking to reduce corrosion-related downtime rather than beginners still deciding on a setup.

Within the PKS Foilite titanium hardware range, this mounting-stud kit sits alongside the Foilite Titanium Track Lock Universal Track Nut, a separate four-pack of dual-threaded track nuts with integrated set screws that lock position inside the track. PKS offers the track nuts as an optional add-on, and the two products together form a complete titanium fastener solution for a Foil Drive installation. Riders who only need the board-side track nuts — without the studs and cone nuts — can purchase those independently at a lower price point.

Compared to generic stainless-steel Foil Drive bolt sets available from other retailers, the Foilite kit commands a premium, justified primarily by the Grade 5 titanium material and the weight reduction it provides. For riders evaluating alternatives, the main decision is whether the corrosion resistance and weight savings warrant the higher cost over standard stainless hardware that may need periodic replacement in saltwater use.
