Construction & Design

The ARP Hex Bolt Kits are constructed from ARP's renowned 8740 chromoly steel, a material known for its excellent strength-to-weight ratio and toughness. The bolts undergo a proprietary heat-treating process that enhances their tensile strength to 180,000 psi, making them suitable for high-performance and heavy-duty applications. The black oxide finish not only provides corrosion resistance but also reduces glare and adds a professional aesthetic. The flanged hex head design allows for easy installation with standard tools, ensuring a secure grip and proper torque application. The precise M12 x 1.75 thread pitch ensures compatibility with a broad range of components, making these bolts a versatile choice for various projects.

Installation & Fitment

Installing the ARP Hex Bolt Kits is straightforward, thanks to their standard metric M12 x 1.75 thread size and flanged hex head design. These bolts are intended as direct replacements or upgrades for existing fasteners in compatible applications. No special tools beyond standard wrenches or sockets are required. Proper torque specifications should be followed to ensure optimal clamping force and safety. The high-quality materials and precise manufacturing mean that no additional modifications, cutting, or drilling are necessary for most applications. Always verify fitment with your specific project requirements before installation.
