ARP Bolts ARP 5/16in-18 12pt Black Oxide Nut Kit, Steel, 10-Pkg, 180,000 psi - 301-8343

Hey there! If you're looking to beef up your ride with some solid hardware, check out this ARP 5/16-18 12-point black oxide nut kit. Seriously, these nuts are the real deal. Each one is made from tough steel, so you know they can handle some serious torque without giving up on you.

Now, let’s get into the nitty-gritty. The thread size is 5/16-18, which makes them a perfect fit for a variety of applications. And with a wrench diameter of 3/8 inches, you won’t need any special tools to get them on or off. Just grab your standard socket set and you’re good to go.

What I really appreciate about these nuts is their finish. The black oxide coating not only looks sleek but also provides some added protection against rust and corrosion. You won’t have to worry about them looking shabby after a few months on the road.

In terms of strength, these nuts are no joke. They’ve got a yield strength of 180,000 psi, which is more than enough for most setups. Whether you’re working on a performance build or just need reliable fasteners for everyday use, this kit has you covered.

Oh, and one more thing: this kit comes with ten nuts, so you’ll have plenty to work with. Just keep in mind, washers aren’t included, so you might want to grab those separately if your project calls for them.

Overall, if you need some solid, dependable nuts that won’t let you down, this ARP kit is a smart choice. They fit like a glove, and you can trust them to keep everything locked down tight.

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.
