ARP Bolts 1/2-20 12pt Nut Kit, Steel, Black Oxide Finish, 150,000 psi Yield Strength - 300-8306

If you're diving into some serious automotive work, you might want to check out the ARP 1/2-20 12pt Nut Kit. These nuts are the real deal for anyone who values quality and durability in their builds. With a thread size of 1/2-20 in. RH, they fit snugly and securely, so you can trust they won't let you down when you need them most.

Now, let's talk about the nut style. These are 12-point nuts, which means you get a better grip compared to your standard hex nuts. That’s a game changer when you're in tight spaces or dealing with stubborn bolts. And while they don't have a nylon insert or self-locking feature, the solid steel construction more than makes up for it. Speaking of which, the steel material is finished with a black oxide coating, giving it that sleek look while also providing some extra corrosion resistance.

When it comes to wrench size, you'll need a 5/8 in. wrench to get these bad boys on and off. And trust me, you'll appreciate the 150,000 psi yield strength these nuts offer. That kind of strength means they can handle the pressure without breaking a sweat. Just keep in mind that they’re sold individually, so if you’re working on a larger project, you might want to grab a few extras.

Overall, if you’re looking for reliable nuts that won't flinch under pressure, this ARP kit is a solid choice. They might not come with washers, but their performance speaks for itself. Whether you're upgrading your Jeep or tackling a custom build, these nuts are worth having in your toolbox.

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.
