Construction & Design

The ARP 12pt Hardware Kit is constructed from 8740 chromoly steel, a material renowned for its exceptional strength-to-weight ratio and toughness. The fasteners undergo a proprietary heat-treatment process that enhances their tensile strength, ensuring they can handle high-stress environments without failure. The black oxide finish provides excellent corrosion resistance, making these bolts suitable for both indoor and outdoor use.

The 12-point (12pt) head design allows for increased torque application and easier installation in tight spaces, providing better grip and reducing the risk of stripping. The precise machining and threading ensure smooth engagement and consistent clamping force, which is critical for maintaining the integrity of your assembly over time.

Performance & Reliability

With a tensile strength rated at 180,000 psi, these ARP chromoly bolts deliver superior performance compared to standard hardware. They are engineered to support increased safety margins and durability, making them ideal for high-performance engines, heavy-duty trailers, or marine environments where corrosion resistance and strength are paramount. Their robust construction helps prevent thread stripping and fastener failure, ensuring your project remains secure under demanding conditions.

Installation & Fitment

The ARP 12pt Hardware Kit is designed for straightforward, bolt-on installation. Its standard M10 x 1.25 thread size makes it compatible with a wide range of components, including engine parts, chassis, and trailer assemblies. No special tools beyond standard wrenches are required, and the precise threading ensures proper engagement and torque application. The heat-treated chromoly construction provides a reliable, long-lasting fastening solution that requires no special maintenance beyond routine inspection.
