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 every detail of your engine build matters, rely on Auto Racing Products (ARP) hex nuts to keep your components locked down. This 7/16-20 thread nut features a 5/8 inch hex head, providing the perfect balance of clearance and torque capability. Engineered from premium chromoly steel, these nuts are designed to withstand the intense vibrations and thermal cycling found in high-output racing engines.
Unlike standard hardware-store nuts, these ARP fasteners undergo rigorous quality control to ensure consistent strength and thread integrity. The black oxide finish provides a clean, professional look while offering protection against oxidation. Whether you are securing intake manifolds, brackets, or other critical engine accessories, these nuts offer the peace of mind that your fasteners will hold under pressure. Their compact 5/8 hex profile is ideal for tight engine bays where clearance is at a premium. Experience the difference that professional-grade hardware makes in your vehicle's reliability.
