Product Details

The ARP 643-2250 is a premium 5-piece bolt kit featuring high-performance 12-point stainless steel fasteners designed for automotive, marine, and trailer applications. These bolts are manufactured from specially alloyed ARP 300 stainless steel with a nominal tensile strength rating of 180,000 psi, providing a substantial safety margin over standard Grade 8 hardware.

Key Features:

  • ARP 300 stainless steel construction for maximum strength and corrosion resistance
  • 12-point head design for superior grip and torque distribution
  • 180,000 psi tensile strength rating exceeds Grade 8 specifications
  • Specially polished finish delivers excellent appearance and rust resistance
  • Maintenance-free performance in harsh environments
  • Includes washers for complete installation
  • 5-piece kit provides convenience for small projects or repairs

ARP's precision manufacturing ensures consistent quality and reliability. The polished stainless steel finish not only provides outstanding corrosion protection for marine and outdoor applications but also delivers a show-quality appearance. These fasteners are ideal for differential installations, engine components, suspension systems, and general automotive applications where strength and durability are critical.
