• Heat Treatment: Precision heat-treated to optimize strength and toughness, ensuring reliable performance under high loads and thermal stress.
• Corrosion Resistance: Finished with a black oxide coating that helps resist rust and corrosion, extending the service life of the fasteners.
• Design & Compatibility: Flanged hex head design provides a secure grip with a standard 5/16˝-24 thread size, suitable for a variety of applications requiring a 0.560-inch underhead length.
• Versatile Use: Perfect for automotive assembly, trailer construction, boat fittings, and other heavy-duty fastening tasks where strength and safety are critical.
• Precision Manufacturing: Manufactured to strict quality standards, ensuring consistent dimensions and reliable torque characteristics.
• Safety Margin: Nominally rated at 180,000 psi tensile strength, these bolts offer an extra margin of safety compared to typical hardware, making them suitable for high-performance and safety-critical applications.

Construction & Design

The ARP Hex Bolt Kits feature a robust design utilizing 8740 chromoly steel, a material renowned for its excellent strength-to-weight ratio and toughness. The bolts are carefully heat-treated to achieve a tensile strength of 180,000 psi, ensuring they can handle high-stress environments without failure. The flanged hex head design allows for easy installation and removal with standard tools, providing a secure grip and reducing the risk of stripping or rounding off the head.

The black oxide finish not only enhances the aesthetic appeal but also provides a layer of corrosion resistance, making these fasteners suitable for both indoor and outdoor applications. The precise manufacturing process ensures consistent thread engagement and torque characteristics, which is essential for maintaining proper clamping force and safety.

Performance & Reliability

Designed for demanding applications, these ARP bolts deliver exceptional performance by maintaining their strength and integrity under thermal and mechanical stress. Their high tensile rating ensures a substantial safety margin, making them ideal for critical assemblies where failure is not an option. Whether used in engine builds, chassis components, or trailer hardware, these fasteners help support your vehicle's safety and performance goals.

Installation & Fitment

These bolts are designed as a direct bolt-in replacement for standard 5/16˝-24 fasteners. Installation is straightforward—simply thread the bolt into the corresponding nut or threaded hole, tighten to the manufacturer’s recommended torque specifications, and you're set. No special tools or modifications are required, making them suitable for both professional shops and DIY enthusiasts.

Always ensure proper torque specifications are followed to maximize safety and performance. The flanged head design helps distribute load evenly, reducing the risk of damage or loosening over time.
