KT Foil Hardware Set / Tool Kit

The KT Foil Hardware Set / Tool Kit is a complete fastener-and-tool package from KT Surfing, designed to supply everything needed for assembling and maintaining KT hydrofoils. Rather than sourcing individual bolts, wrenches, and shims separately, this kit bundles every connection component into a single organized tool box. It serves as both a first-time assembly kit for new foil purchases and a convenient replacement or backup set for riders who want spare hardware on hand. The kit covers all connection points in a KT foil stack — from board-to-mast plate through mast-to-fuselage and fuselage-to-wing joints.

• Mast plate to board: 4× M8x30 Torx bolts, 4× M8 T-nuts
• Mast to fuselage: 2× M8x35 Torx bolts
• Front wing to fuselage: 2× M8x24 Torx bolts
• Back wing to fuselage: 2× M6x20 Torx bolts
• Back wing shim set: 12 shims ranging from −2.5° to +3°
• Mast plate shim: 1° board-to-mast plate shim
• Tools included: T40 Torx wrench (M8), T30 Torx wrench (M6)
• Storage: Plastic tool box

This hardware set is relevant to any rider using KT foils across wing foiling, kite foiling, prone foiling, or SUP foiling. It suits everyone from beginners assembling their first foil to experienced riders maintaining a travel-ready spare kit. The inclusion of a full 12-piece shim set makes it particularly useful for riders who actively experiment with tail wing angle to tune their foil's lift and stability characteristics — something intermediate and advancing riders tend to do as they dial in their setup for specific conditions.

It also works well as a replenishment kit. Bolts and T-nuts wear over time, especially with repeated saltwater exposure, and having a complete backup set prevents a corroded bolt from ending a session. KT's own assembly manual recommends regular disassembly and freshwater rinsing of connection hardware to extend its service life, making spare hardware a practical investment.

KT Surfing offers this hardware kit alongside a separate Carbon Connection Parts Set, which uses carbon fiber components at the connection points. The aluminum version reviewed here is the more affordable option at $57, providing the same bolt specifications and shim set in aluminum construction. All hardware within the KT ecosystem is interchangeable across the brand's foil range, so this single kit covers setups built around any KT mast, fuselage, and wing combination. For riders building a KT foil from individual components rather than purchasing a complete foil package, this kit is an essential add-on since the fasteners and shims are not typically included with individual wings or masts sold separately.
