Construction & Design

The ARP 12pt Hardware Kit features fasteners constructed from 8740 chromoly steel, a material renowned for its exceptional strength-to-weight ratio and toughness. The fasteners are meticulously heat-treated to achieve a tensile strength of approximately 180,000 psi, ensuring they can handle high loads and stresses without failure. The black oxide finish not only offers corrosion resistance but also reduces glare and provides a professional appearance. The 12-point (12pt) head design allows for increased torque application and easier installation or removal in tight spaces, making these bolts suitable for complex assemblies where accessibility is limited.

The manufacturing process includes precision machining and strict quality control standards, ensuring each fastener meets or exceeds industry specifications. The combination of high-quality materials and meticulous craftsmanship results in fasteners that are both reliable and long-lasting, capable of supporting your vehicle or project through demanding conditions.

Performance & Safety

While these ARP bolts are not rated for specific horsepower or torque gains, their superior material properties and manufacturing quality provide a dependable fastening solution that supports the integrity of your build. The high tensile strength and corrosion-resistant finish help maintain optimal performance over time, reducing the risk of fastener failure under high-stress conditions. Whether used in engine assembly, suspension components, or trailer hitch installations, these bolts help ensure your project remains secure and safe.
