Optimise your Foil Drive Assist MAX with titanium split bolts. Designed specifically for US Box housings (rails), these titanium split bolts (sizes M7 or M8) make installing your Assist MAX system a breeze. Thanks to an extended shank that fits directly into the T-nut, alignment is a breeze. Once the bolt is in place, the cap screws on like a cylindrical nut for an ultra-secure lock. The bonus for open-back boxes (slotted): Change your battery in record time! No need to take everything apart: just loosen, slide it out, and you’re back in the water. Material: High-strength titanium. Compatibility: M7 and M8 (requires a T40 Torx key).
