ARP 400-8610 5/16-24 Stainless Steel Flanged Hex Nut Kit, Polished Finish - 400-8610

If you're diving into a project that demands reliability, the ARP 5/16-24 SS Flanged Hex Nut is a solid choice. This isn't just any nut; it's crafted from polished stainless steel, which means it's not only tough but also looks good under the hood or on your rig. The 5/16-24 thread size fits a variety of applications, so whether you're working on your Jeep or tackling a custom build, this nut will hold its own.

Now, let’s talk about the details. With a wrench diameter of 1/2 inch, it’s easy to get a good grip on it during installation. And while it doesn’t come with a nylon insert or a self-locking feature, the flanged design provides a bit more surface area, which helps distribute the load more evenly. That’s a nice touch when you’re pushing your vehicle to its limits.

One of the standout features is its yield strength—140,000 psi. That means this nut is built to withstand some serious pressure, making it a reliable choice for high-performance setups. Just keep in mind, these are sold individually, so if you’ve got a big job ahead, you might want to grab a few extras.

In short, if you’re looking for a durable, reliable nut that won’t let you down, this ARP flanged hex nut fits the bill. It’s straightforward, tough, and ready to take on whatever you throw at it.

The Story Behind ARP Bolts

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.
