Bulkhead Nut #10 Black

The Bulkhead Nut #10 Black from FRAGOLA is a precision-engineered aluminum fitting component designed for high-performance fluid systems in automotive, aerospace, and industrial applications. This #10 AN (Army-Navy) sized bulkhead nut serves as the primary fastening element in sandwich-style bulkhead fittings, securing hose adapters and feed lines through panel walls with reliable mechanical integrity. Engineers and technicians rely on bulkhead nuts when routing hydraulic, fuel, or coolant lines through firewalls, engine blocks, or chassis compartments where space and vibration resistance are critical.

Manufactured from aluminum and finished in black anodized coating, the Bulkhead Nut #10 Black delivers corrosion resistance and a clean aesthetic appearance in both street and competition builds. The black anodize layer protects against oxidation and chemical degradation while maintaining excellent thread engagement with standard #10 AN bulkhead fittings. This nut is engineered to withstand the pressures and thermal cycling inherent in demanding fluid delivery systems, with dimensional precision that ensures consistent fitment across FRAGOLA's compatible bulkhead lineup. The compact geometry—1.6 x 0.75 x 4.1 inches—positions it ideally for tight engine compartment installations.

Professionals building custom fuel systems, hydraulic setups, or coolant circuits benefit from the reliability and finish quality of FRAGOLA's black anodized components, which coordinate seamlessly with modern underhood aesthetics. Installation pairs the nut with a matching #10 AN bulkhead fitting body and compatible hose adapters, creating a leak-free panel feedthrough suitable for motorsports, restoration, and OEM-equivalent applications. Whether you're assembling a street rod, race car, or industrial hydraulic manifold, this single nut is an essential inventory item for any serious fabricator or technician working with AN-standard fluid systems.
