Construction & Design

The ARP 12pt Hardware Kit features a robust design utilizing high-quality 8740 chromoly steel, a material renowned for its exceptional strength-to-weight ratio and durability. The bolts are meticulously heat-treated to achieve a tensile strength of 180,000 psi, ensuring they can handle significant loads without failure. The black oxide finish not only provides corrosion resistance but also reduces glare and enhances the visual appeal of your assembly.

The 12-point (12pt) head design allows for increased torque application and better grip with tools, reducing the risk of stripping or rounding off the fastener during installation or removal. This design is especially beneficial in tight spaces where access may be limited, providing a secure grip with standard sockets.

Performance & Reliability

These ARP fasteners are engineered to provide a reliable, high-performance fastening solution that supports your vehicle's safety and integrity.
