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 M12 x 1.75 Hardware

When precision and strength are required, ARP M12 x 1.75 x 40mm 12pt Black Oxide bolts are the preferred choice for professional engine builders. These fasteners are manufactured to exceed aerospace-grade specifications, providing the reliability needed for high-performance street and track applications. With a focus on durability, these bolts are heat-treated to ensure they maintain their integrity under extreme pressure and heat cycles.

Product Highlights

  • Thread Size: M12 x 1.75
  • Length: 40mm
  • Head Type: 12-Point
  • Material: 8740 Chromoly
  • Finish: Black Oxide
  • Set Size: 5 Bolts

The 12-point head configuration is designed for high-torque applications, allowing for a secure fit in confined engine bay areas where standard socket access might be limited. These bolts are perfect for securing engine mounts, transmission components, or other critical chassis parts where vibration and stress are constant factors. By upgrading to ARP hardware, you eliminate the risks associated with standard hardware store bolts, such as thread stripping or fatigue-induced snapping. The black oxide finish provides a clean, professional look while offering essential corrosion resistance. Invest in the best hardware for your project to ensure long-lasting performance and safety.
