Product Details

The ARP 743-4250 is a premium 5-piece bolt kit featuring fine thread, 12-point head fasteners designed for universal automotive, marine, and trailer applications. These high-performance bolts are manufactured from ARP's specially alloyed 300 series stainless steel, offering exceptional strength, corrosion resistance, and maintenance-free service life.

Key Features:

  • Nominally rated at 180,000 psi tensile strength for superior clamping force
  • Fine thread design for precise torque control and increased holding power
  • 12-point head configuration allows easier access in tight spaces
  • Premium ARP 300 stainless steel construction resists rust and corrosion
  • Specially polished finish for professional appearance
  • Includes washers for complete installation
  • Provides substantial safety margin over standard Grade 8 hardware

ARP fasteners are engineered for demanding applications where reliability and appearance matter. The 12-point head design provides multiple engagement positions for easier installation in confined areas, while the stainless steel construction ensures long-lasting performance without the need for protective coatings or maintenance. Each kit includes five matched bolts with washers, ready for immediate installation.
