Construction & Design

The ARP 12pt Hardware Kit is constructed from 8740 chromoly steel, a material renowned for its high strength-to-weight ratio and durability. The fasteners undergo a specialized heat-treatment process that enhances their tensile strength to 180,000 psi, providing a robust safety margin for critical applications. The black oxide finish not only adds corrosion resistance but also reduces glare and enhances the fasteners' appearance.

The 12-point head design allows for increased contact surface with tools, reducing the risk of stripping and enabling easier access in confined spaces. Each bolt is precisely machined to ensure a perfect fit, promoting even load distribution and reducing the risk of failure under stress. This combination of materials, treatment, and design makes the ARP hardware kit a reliable choice for demanding environments.

Performance & Reliability

Engineered for high-performance applications, these fasteners support increased safety margins and long-term durability. Their superior tensile strength ensures they can handle high loads and vibrations common in automotive and marine settings. The heat-treated chromoly construction resists fatigue and stress cracking, providing consistent performance over time. Whether used in engine assemblies, chassis components, or trailer hardware, these bolts help ensure your project maintains integrity and safety.

Installation & Fitment

The ARP 12pt Hardware Kit is designed for straightforward, bolt-on installation. Its standard M12 x 1.75 thread size makes it compatible with a wide range of existing applications. No special tools beyond standard socket or wrench are required, and the high-quality machining ensures smooth threading and proper torque application. The kit is suitable for use in both new builds and repairs, with no need for modifications or special procedures.
