Construction & Design

The ARP 12pt Hardware Kit features bolts made from 8740 chromoly steel, a material renowned for its high strength-to-weight ratio and toughness. The bolts undergo a rigorous heat treatment process to achieve their impressive tensile strength rating, ensuring they can withstand high torque loads and vibration without stretching or failing. The black oxide finish not only provides corrosion resistance but also reduces glare and enhances the aesthetic appeal of the hardware.

The 12-point (12pt) head design allows for increased torque application and better grip with tools, reducing the risk of stripping or slipping during installation. This design also facilitates easier access in tight or hard-to-reach spaces, making installation more straightforward for mechanics and enthusiasts alike.

Performance & Reliability

These fasteners are built to support demanding applications where safety and performance are paramount. Their high tensile strength ensures a secure fit, reducing the risk of fastener failure under stress. The corrosion-resistant finish maintains integrity and appearance over time, even in harsh environments such as marine or off-road conditions. Whether used in engine assemblies, suspension components, or trailer hardware, the ARP 12pt bolts provide consistent, reliable performance.

Installation & Fitment

The ARP 12pt Hardware Kit is designed for easy, bolt-on installation. The precise thread dimensions ensure compatibility with standard M12 x 1.75 threaded components. No special tools or modifications are typically required beyond standard socket or wrench sets. Always follow torque specifications recommended for your application to ensure optimal safety and performance. These bolts are suitable for both professional and DIY projects, offering a straightforward upgrade over standard hardware.
