ARP Bolts ARP 3/8-24 1/2 Socket 12pt Nut Kit Black Oxide Steel 10 Pack - 300-8392

If you're diving into a project that demands some serious durability, let me tell you about the ARP 3/8-24 1/2 Socket 12pt Nut Kit. This isn’t just any nut kit; it’s a solid set of ten nuts that are built to last. With a thread size of 3/8-24 in. RH, these little guys are perfect for a range of applications, whether you're working on a custom build or just need reliable fasteners for repairs.

What I love about these nuts is their 12-point design. It means you can get a better grip with your wrench, and that’s something you’ll appreciate when you’re working in tight spaces. Speaking of wrenches, you’ll need a 1/2-inch wrench to get these on and off, which is pretty standard and easy to find in any toolbox.

Now, let’s talk material. These nuts are made from high-quality steel with a black oxide finish. This isn’t just for looks; the finish helps protect against corrosion, so you can trust them to hold up even in tough conditions. And with a yield strength of 150,000 psi, you know they're tough enough to handle whatever you throw at them.

One thing to note is that these nuts don’t come with nylon inserts or self-locking features, but honestly, that’s not always necessary depending on your application. Just make sure you’ve got the right setup to keep everything secure. And while there aren’t any washers included, you can always grab those separately if you need them.

In short, this kit is a solid choice if you want reliable, heavy-duty nuts that won’t let you down. Whether you're a DIYer or a small business owner looking to stock up on quality fasteners, this 10-pack has you covered.

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.
