Construction & Design

The ARP Hex Bolt Kits are constructed from premium-grade 8740 chromoly steel, known for its excellent strength-to-weight ratio and toughness. The bolts undergo a rigorous heat-treatment process to achieve a tensile strength of 180,000 psi, ensuring they can handle high-stress loads without deformation or failure. The black oxide finish not only provides corrosion resistance but also reduces glare and adds a sleek appearance suitable for visible engine bays or custom builds.

The flanged hex head design facilitates easy installation with standard wrenches or sockets, providing a secure grip and even torque distribution. The precise machining of threads ensures a perfect fit and consistent torque application, which is essential for maintaining the integrity of assembled components. The 25mm underhead length offers versatility for various applications, from securing engine parts to mounting brackets and accessories.

Performance & Reliability

These ARP fasteners are engineered to deliver consistent, high-performance results in demanding environments. Their superior tensile strength and durable construction help support increased safety margins, especially in high-stress automotive or marine applications. While not designed to increase horsepower directly, their reliable clamping force ensures that your components stay secure under vibration, heat, and dynamic loads. The black oxide finish also helps prevent corrosion, extending the service life of the fasteners in harsh conditions.
