Review ARP Black Oxide 1.25 40mm Uhl 12-point fits M8

The ARP 671-1005 is a high-performance, 1.25 pitch, 40mm, M8, 12-point, UHL (Ultra High Tensile) bolts and nuts set from Automotive Racing Products. This bolt and nut kit is specifically designed for rigorous automotive applications, where superior strength and reliability are paramount.

The M8 thread size of these bolts allows for a generous 8mm thread diameter, providing an increased load capacity compared to standard bolts. The 12-point nuts in this kit offer a higher clamping force and resistance to loosening due to their increased number of contact points with the bolt.

The UHL designation indicates that these bolts and nuts have been manufactured from Ultra High Tensile materials, which ensures they can withstand significant tensile forces without failure. The 1.25 pitch measurement refers to the number of threads per inch, with a higher pitch providing a more rapid thread engagement and improved torque transfer.

The oxide finish on the ARP 671-1005 set offers several advantages. It provides corrosion resistance, ensuring that the bolts and nuts remain in excellent condition even in harsh environments. Additionally, the oxide finish can help prevent galling and seizure during installation, making the bolts easier to thread and tighten.

These bolts and nuts are suitable for various automotive applications, including engine buildings, suspension systems, and drivetrain components, where the demanding conditions require the use of high-strength, reliable fasteners. The ARP 671-1005 set is a must-have for professional mechanics, race teams, and enthusiasts who demand the best from their vehicles.

In summary, the ARP 671-1005 M8, 1.25 pitch, 40mm, UHL, 12-point bolt and nut set is a high-performance, reliable, and durable fastener solution designed specifically for the rigors of automotive applications. Its high-strength materials, increased thread size, and superior thread design make it an essential tool for professional mechanics, race teams, and enthusiasts who demand the best from their vehicles.
