#10 Bulkhead Nut

The #10 Bulkhead Nut from Triple X Race Components is a precision-engineered aluminum fitting designed for high-performance fuel and fluid line systems in motorsports applications. This black anodized fastener is purpose-built for racers, engine builders, and performance technicians who demand reliability in critical hydraulic and fuel delivery circuits. The bulkhead nut serves as the securing element in AN-sized bulkhead fittings, ensuring a leak-free seal at the point where lines penetrate engine blocks, fuel cells, or chassis panels.

Manufactured from aluminum and finished in black anodized coating, this #10 AN (5/8"-18 thread) nut combines lightweight construction with corrosion resistance—critical attributes for fuel systems exposed to heat cycles and moisture. The anodized surface protects against oxidation while maintaining the professional appearance demanded in competition vehicles. Its compact design (2.4 x 0.45 x 2.7 inches) and minimal weight of 0.02 pounds make it ideal for weight-conscious builds without compromising structural integrity. The precise threading ensures proper torque retention and prevents vibration-induced loosening during high-performance operation.

This bulkhead nut is essential for drag racers, road course competitors, and street performance enthusiasts running fuel-cell-equipped vehicles or modified fuel systems. It pairs with AN-10 bulkhead fittings to create secure penetration points in aluminum or composite fuel cells and engine bay components. Installation requires standard AN wrenches and should be torqued to manufacturer specifications to prevent leakage while avoiding over-tightening of the aluminum fitting body. Sold individually, users may need multiple units depending on fuel system configuration and the number of bulkhead access points required.
