Construction & Design

The ARP 12pt Hardware Kit features meticulously crafted fasteners made from 8740 chromoly steel, a material renowned for its strength and toughness. Each fastener undergoes a proprietary heat-treatment process to achieve a tensile strength of 180,000 psi, providing a robust safety margin for critical applications. The black oxide finish not only enhances corrosion resistance but also offers a professional, finished look suitable for high-performance builds.

The 12-point head design allows for increased torque application and better engagement in tight or hard-to-reach areas, reducing the risk of stripping or rounding off the fastener head. This design also facilitates easier installation and removal, especially in confined spaces where a standard hex head might be difficult to access. The precision-machined threads ensure a proper fit, enabling accurate torque application and secure fastening.

Performance & Reliability

Engineered for demanding automotive environments, these fasteners provide consistent performance under high stress and temperature conditions. Their high tensile strength and heat-treated construction help prevent stripping, stretching, or failure during intense driving or heavy loads. Whether used in engine assembly, suspension mounting, or other critical components, these bolts deliver peace of mind and long-lasting reliability.
