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.
For applications requiring a larger diameter fastener, the Auto Racing Products 5/16-24 x .560 12-point bolt kit offers the strength and reliability you need. These bolts are manufactured from premium stainless steel, providing a polished finish that resists corrosion and adds a clean, professional touch to your engine bay. Designed for universal use, they are perfect for critical mounting points that require high clamping force.
The 12-point head design is engineered to withstand higher torque levels than standard hex heads, making these bolts ideal for high-vibration environments. The 5/16-24 fine thread pitch ensures a secure fit, preventing loosening over time. Whether you are assembling a race engine or restoring a classic, these bolts provide the peace of mind that comes with using top-tier hardware. Their polished appearance ensures that your engine bay looks as good as it runs, while the stainless steel material guarantees long-term durability against the elements.
