Working on headers? These ARP bolts are the real deal! Made from premium stainless steel that won't rust or weaken from heat, these 3/8 x 1.000 inch bolts are built tough. The 12-point design makes them super easy to tighten even in tight spaces where regular wrenches won't fit. They're rated at 170,000 PSI tensile strength - way stronger than your average Grade 8 hardware. The kit comes with 16 bolts (part number 400-1210) and everything you need for installation. ARP is the go-to brand for serious engine builders, and these header bolts show why. They include that nut-starter nose to prevent cross-threading, making installation smoother. Perfect for Chevy small blocks, big blocks, and plenty of other applications. Factory sealed and ready to make your header install way easier!
