Product Details

The ARP 622-3250 is a premium 5-piece standard hex bolt kit designed for high-performance automotive, marine, and trailer applications. Each kit includes washers and features ARP's specially alloyed 300 stainless steel or heat-treated 8740 chrome moly fasteners with superior corrosion resistance and exceptional strength.

Key Features:

  • Nominally rated at 180,000 psi tensile strength for substantial safety margin over Grade 8 hardware
  • Available in ARP 300 stainless steel (polished finish) or 8740 chrome moly (black oxide finish)
  • Standard hex head design for universal compatibility
  • Rust-resistant stainless steel construction is virtually maintenance-free
  • Includes washers for complete installation
