MIA's Description

The ARP 400-1110 is a header bolt kit designed for high performance automotive applications. These bolts are constructed from ARP Stainless steel and feature a polished finish. Each kit includes 16 bolts with a 3/8 in.-16 thread size and a 1.000 in. underhead length. Washers are included.

The material boasts a tensile strength of 180,000 psi, exceeding Grade 8 steel. The compact hex head design allows for easier socket access in tight spaces near headers. These bolts are noted for being highly corrosion-resistant and heat-resistant. Special attention is recommended: anti-seize should be used on all stainless steel fasteners.
