If you're diving into a header swap or just need some solid bolts for your exhaust system, check out this ARP 3/8in x 1.000 SS 12pt Header Bolt Kit. These aren’t just any bolts; they’re designed for folks who want reliability and a bit of flair under the hood.
First off, let's talk about the fastener style. These are bolt-style fasteners, which means you get a secure fit that you can trust. The thread size is 3/8-16, perfect for a lot of setups out there. The head style features a 12-point design, giving you better grip and torque when you’re tightening things down. No more worrying about stripping heads when you're cranking them on.
With an underhead length of 1.000 inches (or 25.00mm for those who prefer metric), these bolts fit snugly without sticking out too much, keeping your setup clean and tidy. Plus, they're made from stainless steel, which means they won’t rust or corrode over time. That polished finish? It’s not just for looks; it helps with resistance to the elements, ensuring your investment holds up.
This kit comes with 16 bolts, so you’ll have enough to cover your headers without scrambling for extras. Whether you’re a DIY enthusiast or a pro in the garage, these bolts are a solid choice for your next project. Just make sure you’re using them in applications where they fit correctly, and you’ll be good to go!

ARP (Automotive Racing Products) was founded by Gary Holzapfel in 1968 when he noticed his drag-racing friends succumbing to bolt-induced engine failure as a result of poor-quality fasteners. He drew upon his expertise in the aerospace industry to develop a solution, which turned into a successful business nonetheless.
Since its inception, ARP has been engineering and perfecting a wide range of bolts, studs, nuts, and other fasteners for engines, cylinder heads, headers, wheels, and transmissions. Today, ARP remains the undisputed world leader in automotive fasteners. Racing aficionados everywhere know and recognize the ARP brand and can vouch for its quality.
What Makes ARP Bolts So Special?Located in Ventura, California, all ARP processes from raw wire to finished fasteners are conducted in-house, right here in the USA. The company continually improves its processes with strict quality control guidelines and is dedicated to producing products that are second to none. Simply put, ARP Bolts are better than the competition because of their quality materials and advanced processes.
ARP prides itself on using only top-quality materials that are above the usual “aerospace-grade” quality that other manufacturers settle for. For example, while 8740 Chromoly steel has four different grades, ARP only uses the top two, SDF and CHQ. These grades cost twice as much as the lower commercial and aircraft grades, but deliver “zero defect” quality that you can trust each and every time.
ARP Bolts are built to withstand serious racing, possess greater tensile strengths, and can survive higher stress levels than most aircraft fasteners. ARP is dedicated to creating fasteners that boast ultimate strength and durability to ensure they last race after race. Its product lineup ranges from quality high-performance OEM parts to exotic specialty hardware for IndyCar, NASCAR, NHRA drag racing, Formula 1, and even marine applications.
