ARP 1/4-28 12pt Nut Kit, Steel Black Oxide Finish, 150,000 psi Yield Strength - 300-8300

If you're looking to beef up your ride with some solid hardware, check out the 300-8300 ARP 1/4-28 12pt Nut. This isn't just any nut; it's designed for folks who take their vehicles seriously. With a thread size of 1/4-28 in. RH, it fits snugly where you need it, ensuring that everything stays tight and secure on those bumpy trails.

Now, I know what you're thinking—what’s the deal with the 12-point style? Well, it gives you a better grip, which means you can really torque it down without stripping it out. The wrench diameter is 5/16 in., so make sure you’ve got the right tools on hand when you’re ready to install. And if you're curious about the material, it's made from tough steel with a black oxide finish. That not only looks good but also helps resist rust and corrosion—perfect for those of us who like to take our rigs off the beaten path.

One thing to note is that this nut doesn’t have a nylon insert or a self-locking feature, so it’s all about that tight fit and proper torque to keep things secure. It boasts a fastener yield strength of 150,000 psi, which means it can handle some serious stress without giving in. Just remember, these are sold individually, so grab what you need for your project.

All in all, the ARP 1/4-28 12pt Nut is a solid choice for anyone who wants to ensure their setup is as tough as they are. Whether you're in the garage or out on the trail, you want hardware that you can trust, and this nut delivers.

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.
