Product Details

The ARP 612-1250 is a premium 5-piece bolt kit featuring high-quality stainless steel fasteners with 12-point heads. These professional-grade bolts are manufactured from specially alloyed ARP 300 stainless steel, nominally rated at 180,000 psi tensile strength, providing a substantial safety margin over standard Grade 8 hardware.

Key Features:

  • ARP 300 stainless steel construction for superior strength and corrosion resistance
  • 12-point head design for improved grip and precise torque application
  • 180,000 psi tensile strength rating exceeds Grade 8 specifications
  • Polished stainless finish resists rust and requires no maintenance
  • Includes washers for complete installation
  • Ideal for automotive, marine, and trailer applications

ARP fasteners are engineered for professional and enthusiast use where reliability and appearance matter. The stainless steel construction ensures these bolts will maintain their attractive polished appearance while delivering exceptional clamping force in demanding applications.
