About ARP

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.

Premium ARP 12-Point Black Oxide Fasteners

When building a high-performance engine, fastener integrity is non-negotiable. These ARP M8 x 1.25 x 65mm 12pt bolts are engineered to provide superior clamping force and reliability for your most demanding fabrication projects. Finished in a durable black oxide coating, these bolts resist corrosion while maintaining the high-tensile strength ARP is famous for.

Key Features and Technical Specs

  • Size: M8 x 1.25 thread pitch
  • Length: 65mm under-head length
  • Head Style: 12-point design for high-torque clearance
  • Material: High-strength alloy steel with black oxide finish
  • Quantity: Sold in a convenient 5-piece package

Whether you are securing intake manifolds, accessory brackets, or custom fabrication components, these ARP fasteners ensure your build stays together under extreme vibration and thermal cycling. The 12-point head design allows for easier access in tight engine bay configurations where standard hex heads might fail to fit. By choosing ARP, you are investing in the gold standard of racing hardware. Trust your build to the industry leader in fastener technology. Find these and other essential engine components at GGCRACING.
