Construction & Design

The ARP Hex Bolt Kits are meticulously manufactured from 8740 chromoly steel, a material renowned for its exceptional strength-to-weight ratio and toughness. The bolts are precision-machined to exact specifications, ensuring a perfect fit and consistent performance. The black oxide finish not only enhances corrosion resistance but also reduces glare and provides a professional appearance suitable for show or race applications.

The flanged hex head design allows for easy tightening and loosening with standard wrenches or sockets, providing a secure grip and reducing the risk of stripping or rounding off the head. The heat treatment process ensures that each bolt maintains its tensile strength and structural integrity even under extreme conditions, making them suitable for high-stress environments.
