ARP (Automotive Racing Products) makes the strongest fasteners in motorsport — head studs, main studs, rod bolts, and flexplate bolts used by every Formula 1, NHRA, NASCAR, and championship motorsport program. Aerospace-grade alloys, exact-fit machining.
When precision and reliability matter, choose Auto Racing Products. These 5/16-18 12-point flange nuts are designed to provide superior clamping force for critical engine assemblies. Crafted from high-strength chromoly steel, these fasteners are heat-treated to withstand the intense vibrations and thermal cycling found in high-performance racing engines.
The integrated flange design distributes clamping pressure more effectively than standard fasteners, reducing the risk of loosening under load. The 12-point head configuration is perfect for tight clearances, allowing for consistent torque application in restricted spaces. Finished in a rugged black oxide, these nuts resist corrosion while maintaining a clean, professional aesthetic. Ideal for intake manifolds, valve covers, and various accessory brackets, these nuts are a must-have for any serious mechanic or DIY performance enthusiast. Whether you are restoring a classic or building a modern track machine, ensure your hardware is up to the task. Experience the difference in quality and performance with these essential components available at GGCRACING.
