Construction & Design

These ARP hex bolts are meticulously manufactured from 8740 chromoly steel, a material renowned for its exceptional strength-to-weight ratio and toughness. The heat-treatment process ensures the bolts can withstand high stress and temperature conditions, making them suitable for both high-performance and heavy-duty applications. The black oxide finish not only enhances corrosion resistance but also reduces glare and provides a professional appearance.

The flanged hex head design allows for easy torque application and secure tightening, reducing the risk of stripping or slippage during installation. The 7/16 in.-14 thread size is a common standard, ensuring compatibility with a wide variety of components and assemblies. The underhead length of 1.750 inches provides sufficient thread engagement for secure fastening, even in thicker materials or assemblies requiring extra holding power.

Performance & Reliability

Designed for demanding environments, these ARP fasteners deliver consistent performance and peace of mind. Their high tensile strength ensures they can handle increased loads and stresses, making them ideal for performance builds, off-road vehicles, and applications where safety is paramount. The heat-treated chromoly construction resists stretching and fatigue, maintaining integrity over time and under vibration.
