Product Details

ARP 400-1212 is a premium 16-piece header bolt kit featuring 12-point heads for superior fastening in exhaust header applications. These bolts are manufactured from black oxide coated chrome moly steel with a nominal tensile strength of 170,000 psi, substantially stronger than standard Grade 8 hardware.

Key Features:

  • 16-piece complete bolt kit for header installation
  • 12-point head design allows socket access in tight spaces near exhaust pipes
  • Chrome moly construction with black oxide finish for corrosion resistance
  • 170,000 psi tensile strength exceeds Grade 8 specifications
  • Includes premium-quality washers for proper installation
  • Precision-manufactured threads prevent cross-threading during installation

This kit provides everything needed for secure header mounting with the durability and strength demanded by high-performance and racing applications. The 12-point head configuration offers more contact points than standard hex bolts, reducing the risk of rounding and allowing installation in confined engine bay spaces.
