Armstrong A+ System Foil Screw Set

The Armstrong A+ System Foil Screw Set is a complete hardware kit designed to assemble and secure Armstrong's A+ Carbon and Performance Carbon mast setups. Sold by Armstrong under the SKU "Aplus_Hardware_Set," this set contains all the fasteners, barrel nuts, shims, and tools needed to connect the mast to the Titanium Carbon fuselage, front wing, and stabilizer. The hardware is built from 316L stainless steel and titanium — materials chosen for corrosion resistance and durability in saltwater environments.

The set ships with eleven screws and fasteners, two polycarbonate pro shims for fine-tuning stabilizer angle, and both a T30 Torx driver bit and a T30 L-shaped Torx tool so riders can assemble or adjust their foil on the water without carrying a separate toolkit.

• Mast-to-fuselage / wing screws: 5x Torx M6 28.5mm 316L stainless steel countersunk (rainbow titanium coating)
• Short countersunk screw: 1x Torx M6 19.5mm 316L stainless steel (gold titanium coating)
• Barrel nuts: 2x Torx M6 8mm titanium
• Dome head screws: 2x Torx M6 17mm 316L stainless steel (rainbow titanium coating)
• Shims included: 0.5° polycarbonate pro shim (blue), 1° polycarbonate pro shim (red)
• Tools included: 1x T30 Torx driver bit, 1x T30 L-shaped Torx tool
• Screw drive type: Torx T30
• Material: 316L stainless steel with titanium coating; titanium barrel nuts

This hardware set is aimed at any rider running an Armstrong A+ Carbon or Performance Carbon mast who needs a fresh set of fasteners — whether building up a new foil, replacing corroded or stripped screws, or keeping a spare kit in a gear bag. Because the set covers the mast-to-fuselage, front-wing, and stabilizer connections, it functions as a one-box solution for the lower assembly. It does not include the mast-top hardware that bolts the mast to the board, so riders replacing that connection will need to source those fasteners separately.

The included polycarbonate pro shims are a practical addition for intermediate and advanced riders who want to experiment with stabilizer angle. The shims allow adjustments at half-degree increments, giving riders a straightforward way to tune lift and pitch response without purchasing shims individually.

Within Armstrong's own hardware catalog, this set sits alongside the M7 Screw Set, which serves the older M7 Performance mast platform using smaller M7 fasteners. Riders upgrading from an M7 mast to an A+ Carbon or Performance Carbon mast will need this A+ set, as the two systems use different fastener sizes and connection geometry. Armstrong also sells the Performance Mast Top Hardware separately for the board-side connection, which complements this kit.

At the $42.99 price point, the set is comparable to other brand-specific titanium and stainless foil hardware kits on the market. Because Armstrong uses a proprietary assembly design rather than a universal bolt pattern, aftermarket substitutes are not a direct option — making this the standard replacement and spare-kit choice for A+ system owners.
