If you're diving into some serious engine work or just looking to spruce up your Chevy, you might want to check out the ARP SB Chevy SS Hex Header Bolt Kit. Trust me, these aren’t just any bolts; they’re a solid upgrade if you want something that can handle the heat and stress of high-performance setups.
First off, let’s talk about the material. These bolts are made from stainless steel, which means they’re not just tough but also resistant to rust and corrosion. If you’ve ever dealt with rusty bolts, you know how frustrating that can be. The polished finish gives them a nice touch too, so they’ll look good whether you’re showing off your ride or just working under the hood.
Now, onto the specs: you’re looking at a fastener style that’s a bolt with a thread size of 3/8-16 inches. The hex head style makes it easy to get a good grip on them, so you won’t be fumbling around when you’re tightening things up. The underhead length is 1.000 inches (or 25.00 mm for those who prefer metric), which is just right for most header applications.
And here’s the kicker: you get all of this in a set of 12. That’s perfect for those of us who like to keep a few extras on hand, just in case. Whether you're replacing worn-out bolts or just want to make sure you have the right hardware when you need it, this kit has got you covered.
In short, if you’re looking for reliability and a bit of style for your Chevy, these ARP bolts are definitely worth considering. They’ve got the durability to stand up to the rigors of performance driving, and they’ll keep your headers securely in place without any fuss.

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.
