Key Features

ARP Hex Bolt Kits incorporate several advanced features that set them apart from standard hardware. These fasteners are made from ARP's proprietary 8740 chromoly steel, a material renowned for its exceptional strength and toughness. The bolts are heat-treated to achieve a tensile strength rating of 180,000 psi, offering a significant safety margin over typical Grade 8 hardware. This ensures that your components remain securely fastened under demanding conditions, including high-stress engine environments or off-road use.

• Premium Material: 8740 chromoly steel for maximum strength and durability.
• Heat Treatment: Specially heat-treated to 180,000 psi tensile strength for enhanced safety and performance.
• Finish: Black oxide coating provides corrosion resistance and a professional look.
• Design: Flanged hex head for easy installation and removal with standard tools.
• Application Versatility: Suitable for automotive, boat, trailer, and other high-stress fastening needs.
• Precision Manufacturing: Manufactured to strict quality standards for consistent performance.

Construction & Design

The ARP Hex Bolt Kits feature a robust design optimized for strength and reliability. The bolts are machined from ARP's proprietary 8740 chromoly steel, which is known for its exceptional toughness and fatigue resistance. The heat treatment process ensures that each fastener maintains its tensile properties even after exposure to high temperatures and stress cycles. The flanged hex head design allows for easy torque application with standard wrenches or sockets, ensuring secure fastening without damaging the bolt head.

The black oxide finish not only enhances corrosion resistance but also reduces glare and provides a clean, professional appearance. The underhead length of 4 inches offers versatility for various mounting depths and applications, making these bolts suitable for a wide range of projects requiring high-strength fasteners.

Performance & Reliability

Designed for demanding environments, these ARP bolts provide a substantial safety margin and consistent performance. Their high tensile strength ensures that they can withstand the stresses encountered in high-performance engines, off-road adventures, or marine conditions. The heat-treated chromoly construction helps prevent stretching or failure under load, contributing to the overall safety and longevity of your assembly.

Installation & Fitment

Installing the ARP Hex Bolt Kits is straightforward, thanks to their standard hex head design. These bolts are intended as direct replacements for SAE 3/8˝-24 fasteners and can be used in a variety of applications where high-strength bolts are required. No special tools or modifications are necessary, and proper torque specifications should be followed to ensure optimal clamping force and safety. Always consult your vehicle or equipment manufacturer’s guidelines for specific torque values.
