• Flanged Hex Head: The flanged hex head design allows for easy installation and removal with standard tools, providing a secure grip and even load distribution.
• Optimal Length: Underhead length of 35mm ensures proper engagement and clamping force for various assembly needs.
• Versatile Use: Suitable for automotive, boat, trailer, and other industrial applications requiring high-strength fasteners.
• Safety Margin: The high tensile strength provides an extra margin of safety, making these bolts ideal for critical and high-stress applications.
• OEM-Quality Manufacturing: Manufactured to strict standards, ensuring consistent quality and performance in every kit.

Construction & Design

The ARP Hex Bolt Kits feature a robust design centered around their 8740 chromoly steel construction, renowned for its exceptional strength-to-weight ratio. Each bolt is precision-machined to exact specifications, ensuring a perfect fit and reliable performance. The heat-treatment process enhances the tensile strength, allowing these fasteners to withstand high torque loads without stretching or failing.

The black oxide finish not only adds a sleek, professional appearance but also provides a protective barrier against corrosion and rust, making these bolts suitable for both indoor and outdoor use. The flanged hex head design simplifies installation and removal, reducing the risk of stripping or cam-out during tightening or loosening. Overall, the design emphasizes durability, ease of use, and long-term reliability.

Performance & Reliability

Designed for demanding applications, the ARP Hex Bolt Kits deliver outstanding performance by combining high tensile strength with superior material quality. These bolts are ideal for securing critical components where failure is not an option. Their strength and corrosion resistance make them suitable for high-performance engines, chassis assemblies, and marine environments.

While these bolts are not specifically rated for racing or extreme off-road use, their high-quality construction ensures they perform reliably in everyday driving, spirited street use, and professional installations. They help support your vehicle’s safety and integrity, giving you confidence in your assembly work.

Installation & Fitment

Installing the ARP Hex Bolt Kits is straightforward, thanks to their standard M10 x 1.50 thread size and flanged hex head. These fasteners are designed to bolt directly into compatible threaded holes without the need for modifications. No cutting, drilling, or special tools are required beyond standard wrenches or sockets.

Ensure proper torque specifications are followed during installation to achieve optimal clamping force and prevent over-tightening. These bolts are suitable for a wide range of applications, including engine assemblies, suspension components, and structural mounts, making them a versatile choice for both professional mechanics and DIY enthusiasts.
