Construction & Design

The ARP Hex Bolt Kits feature a robust construction utilizing 8740 chromoly steel, a material renowned for its high strength-to-weight ratio and durability. The bolts are meticulously heat-treated to achieve a tensile strength of 180,000 psi, providing a significant safety margin for demanding applications. The black oxide finish not only enhances corrosion resistance but also offers a professional, finished look suitable for visible engine components or structural assemblies.

The flanged hex head design ensures a secure grip with standard wrenches or sockets, facilitating straightforward installation and removal. The 100mm underhead length offers versatility, accommodating various component thicknesses and mounting configurations. These design choices collectively contribute to a fastener that is both reliable and easy to work with, even in tight or challenging spaces.

Performance & Reliability

Designed for high-stress environments, these ARP bolts deliver consistent performance under extreme conditions. Their superior tensile strength ensures that they can withstand significant loads without stretching or failing, making them suitable for critical fastening points in your vehicle or equipment. The heat treatment process enhances fatigue resistance, ensuring long-term durability even after repeated cycles of stress and temperature fluctuations.

Installation & Fitment

Installing the ARP Hex Bolt Kits is straightforward, thanks to their standard metric thread size and flanged hex head. These bolts are designed to bolt directly into compatible threaded holes without the need for modifications. No special tools or procedures are required beyond standard hand or power tools, making them accessible for both professional mechanics and DIY enthusiasts.

Ensure that the mating threads are clean and properly lubricated if necessary, to achieve optimal torque and fastening security. Always follow manufacturer torque specifications to prevent over-tightening or damage.
