ARP SB Chevy 3/8 x .750in 12pt Header Bolt Kit

These ARP header bolts feature a 12-point head, which is a smart choice when working in tight spaces. A standard 6-point socket can sometimes slip or round off a bolt head if there isn't much room to maneuver, but the 12-point design gives your socket more contact points, making it easier to get a solid grip and turn the bolt without damaging it. This is especially helpful when you're installing headers on a Small Block Chevy, where access can be pretty limited.

The bolts themselves are made from strong, heat-treated steel, which is important because headers get hot. This material helps them resist stretching and corrosion, ensuring a secure seal between your headers and the engine block over time. Each bolt measures 3/8 inch in diameter and is 0.750 inches long, a common size for many header applications on these engines. ARP is well-known for making solid hardware, and this kit is no exception, offering a reliable way to get your headers bolted down correctly.
