Description
Product Overview
ARP’s 100-1110 header bolts are a premium solution designed for enthusiasts and professional mechanics who demand reliability and performance from their exhaust systems. Constructed from Grade 8 Chrome Moly steel, each bolt offers a superior tensile strength that exceeds standard automotive fasteners, while the black oxide finish adds a layer of corrosion resistance to protect against the harsh environment of high‑temperature exhaust gases. The 3/8‑16 UNC thread size and hex head style provide a universally compatible fit for a broad range of header designs, making installation straightforward and secure. Packaged as a set of 16, these bolts ensure you have enough hardware for complete header assembly or replacement, reducing the need for multiple purchases and simplifying inventory management.
