Foil Drive Titanium M7 Mast Plate Split Bolt MAX

The Foil Drive Titanium M7 Mast Plate Split Bolt MAX is a titanium hardware upgrade designed specifically for the Foil Drive Assist MAX electric foil-assist system. Manufactured by Foil Drive, an Australian brand focused on electric-assist foiling equipment, this split bolt set replaces the standard mast plate bolts with a two-piece stud-and-cap design that stays fixed in your board's track inserts. The split bolt concept addresses a common frustration with electric foil-assist setups: the time and fiddling required to align and thread bolts into recessed T-nuts when mounting the system or swapping batteries between sessions.

Each bolt consists of an extended stud that remains fixed to the T-nut in your board's track, plus a cap that threads onto the exposed stud once the mast plate is in position. The result functions similarly to a barrel nut, letting you secure the Assist MAX mast plate without having to hunt for T-nut slots or deal with loose hardware. The M7 thread size suits foil brands that use M7 mast-mounting hardware, while Foil Drive also offers an M8 variant for boards with M8 track inserts.

This hardware is aimed at Foil Drive Assist MAX owners who want to streamline their setup and teardown routine, particularly riders who regularly swap batteries between sessions or during downwind runs with trench-style battery changes. The titanium construction offers meaningful corrosion resistance for saltwater use and saves weight compared to stainless steel alternatives, which matters for riders conscious of every gram in their foil setup.

The split bolt design is most valuable for riders who frequently mount and dismount their Assist MAX system — for example, those who share a board between powered and unpowered sessions, or who travel and need to break down their gear regularly. Riders who install their system once and leave it mounted will see less benefit from the quick-alignment feature.

Within Foil Drive's bolt and hardware collection, the Titanium Mast Plate Split Bolt sits at the top of the range at AUD $200, well above the standard Assist MAX Mast Plate Bolts (AUD $40) and even the Assist MAX Titanium Mast Plate Bolts (AUD $90), which use titanium but lack the split-bolt mechanism. Foil Drive also sells split bolt hardware for their Assist Slim system and a Carbon Integrated Mast M5 Split Bolt for specific mast setups. The MAX designation distinguishes this product from Assist PLUS and Assist Slim hardware, which uses different mounting geometry. Riders should confirm whether their board uses M7 or M8 track inserts before purchasing, as both sizes are available separately.
