Construction & Design

The ARP 12pt Hardware Kit features high-quality 8740 chromoly steel, a material renowned for its excellent strength-to-weight ratio and toughness. Each bolt is meticulously heat-treated to achieve a tensile strength of 180,000 psi, providing a substantial safety margin for demanding applications. The black oxide finish not only offers corrosion resistance but also reduces glare and provides a professional appearance.

The bolts are precision-machined with a 12-point (12pt) head design, allowing for better torque application and easier installation in tight spaces. The 12-point configuration provides increased contact surface with tools, reducing the risk of stripping or rounding off the head during installation or removal. This design ensures a secure fit and reliable torque transfer, critical for high-stress environments.

Performance & Reliability

Built for strength and durability, these fasteners are ideal for applications where safety and performance are paramount. The high tensile rating ensures they can handle significant loads, making them suitable for critical components in automotive and industrial settings. The heat-treated chromoly construction guarantees longevity and resistance to fatigue, even under repeated stress.

Installation & Fitment

The ARP 12pt Hardware Kit is designed for straightforward installation. The bolts are compatible with standard M12 x 1.5 threaded components, making them suitable for a wide range of vehicles and equipment. No special tools are required beyond standard socket or wrench sets. The precise manufacturing ensures a proper fit, and the high-quality materials help prevent stripping or cross-threading.

Whether you're replacing worn hardware or building a new assembly, these bolts provide a reliable, high-performance fastening solution. Always ensure proper torque specifications are followed during installation to maximize safety and performance.
