ARP Bolts 3/8-24 1/2" Socket 12pt Nut Kit, Steel, Black Oxide Finish, 150,000 psi - 300-8371

If you're looking for a solid nut to keep your projects tight and secure, let me tell you about the 300-8371 ARP 3/8-24 1/2 Socket 12pt Nut Kit. This isn't just any nut; it's built to handle the kind of stress that would make lesser fasteners buckle. With a thread size of 3/8-24 in. RH, it fits perfectly for a range of applications, especially if you're into off-roading or tinkering with your Jeep.

Now, I know what you might be thinking—what's the deal with the nut style? Well, this one's a 12-point design, which gives you a better grip and allows for more torque. That means you can really crank it down without worrying about stripping it. And while it doesn’t have a nylon insert or self-locking feature, the black oxide finish on this steel nut adds a layer of corrosion resistance. It’s tough enough to withstand the elements, whether you're out on the trails or just dealing with everyday wear and tear.

One thing to note is that it has a wrench diameter of 1/2 in., so make sure you’ve got the right tools handy when you’re ready to install. The yield strength is impressive too, clocking in at 150,000 psi. That’s some serious strength right there. Just remember, these nuts are sold individually, so grab as many as you need for your next project.

In short, if you want reliability and strength in a fastener, this nut kit is a solid choice. It’s straightforward, no-nonsense, and gets the job done without any fluff. You’ll appreciate the quality when you’re out there putting your vehicle through its paces.

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.
