Show original supplier description
The ARP Stainless 400-1102 is a premium engine fastener kit specifically engineered for the installation of exhaust headers. The kit includes 16 bolts, each measuring 3/8 in.-16 with a 0.750 inch underhead length, along with matching washers. These ARP bolts offer a substantial upgrade over standard Grade 8 hardware, with a nominal tensile strength of 170,000 psi. The polished stainless steel finish not only enhances aesthetics but also provides long-lasting protection against the elements. The compact hex head design allows for easy access with a socket, even in tight spaces adjacent to the headers. Each component is manufactured to ARP's high standards, ensuring a secure and reliable fit for your header installation.
