If you’re looking to add a bit of flair to your engine bay, check out this ARP SS Valve Cover Bolt Kit (part number 400-7502). These bolts are not just about looks; they’re built to last. Made from polished stainless steel, they resist corrosion and keep your setup looking sharp for years to come.
Now, let’s dive into the details. These bolts come with a 12-point head style, which means you’ll get a solid grip when tightening them down. The thread size is 1/4-20 inches, and they’re 0.515 inches long—perfect for most valve covers without any fuss. Plus, you won’t have to worry about losing grip over time; these bolts are designed to hold up under pressure.
One nice touch is that this kit includes washers, which helps distribute the load and keeps everything snug. Just a heads-up, though—there aren’t any hold-down tabs in this package, so make sure you’ve got that covered if your setup needs it.
Whether you’re going for a clean look in your daily driver or you’re building a show car, these bolts are a solid choice. They fit well and keep everything in place, so you can focus on what really matters—getting out on the road and enjoying the ride.

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.
