• Nominal Tensile Strength: Rated at 180,000 psi, these bolts offer a substantial safety margin over typical Grade 8 hardware, supporting your vehicle's performance and safety needs.
• Underhead Length: The 25mm length provides ample engagement for most standard applications, ensuring a secure and reliable fastening solution.

Construction & Design

The ARP Hex Bolt Kits are meticulously engineered from ARP's renowned 8740 chromoly steel, a material celebrated for its exceptional strength-to-weight ratio and toughness. Each bolt is precisely machined to exact specifications, ensuring a perfect fit and consistent performance. The flanged hex head design facilitates easy tightening and loosening with standard wrenches or sockets, while the black oxide finish not only adds a sleek appearance but also enhances corrosion resistance.

The heat treatment process involves controlled heating and quenching, which optimizes the microstructure of the steel, resulting in a fastener that can withstand high tensile loads and cyclic stresses. This makes the ARP bolts ideal for high-performance applications where safety and reliability are paramount. The robust construction ensures that these bolts maintain their integrity over time, even under extreme conditions.
