Construction & Design

The ARP Hex Bolt Kits are constructed from 8740 chromoly steel, a material renowned for its excellent strength-to-weight ratio and toughness. The bolts are meticulously heat-treated to achieve a tensile strength of 180,000 psi, ensuring they can handle high-stress environments without failure. The black oxide finish not only provides corrosion resistance but also reduces glare and enhances the bolt's appearance.

The flanged hex head design facilitates straightforward installation and removal with standard wrenches or sockets, while the 50mm underhead length offers flexibility for various mounting depths. These features combine to produce a fastener that is both robust and user-friendly, capable of maintaining secure connections over extended periods and under challenging conditions.
