Construction & Design

The ARP 12pt Hardware Kit features a robust design centered around high-quality 8740 chromoly steel, a material renowned for its strength and toughness. The fasteners undergo a proprietary heat treatment process that enhances their tensile strength and fatigue resistance, making them suitable for high-stress applications. The black oxide finish not only provides corrosion resistance but also reduces glare and adds a professional appearance to your assembly.

The 12-point (12pt) head design allows for increased torque application and better grip with tools, reducing the risk of stripping or rounding off the fastener head during installation or removal. This design is especially beneficial in tight spaces where access may be limited. The precise manufacturing tolerances ensure a consistent fit, enabling secure fastening and long-term reliability.
