ARP 400-8303 7/16-20 Stainless Steel 12pt Nut Kit, Polished Finish, Sold Individually - 400-8303

So, you’re looking to beef up your ride with some quality nuts? Let me tell you about the ARP 7/16-20 Stainless Steel 12-Point Nut. This isn’t just any nut; it’s built for those who really care about performance and durability.

First off, the thread size is 7/16-20 in. RH, which means it’s perfect for a range of applications. Whether you're working on your Jeep or any other project that needs reliable fastening, this nut fits the bill. The 12-point design isn’t just for looks; it gives you a better grip and allows for more torque without slipping, which is a game-changer when you're trying to get everything just right.

Now, I know some folks worry about the nylon insert or self-locking features, but let me assure you, this nut stands strong on its own. Made from polished stainless steel, it not only looks good but also resists corrosion like a champ. You won’t have to worry about rust ruining your hard work. Plus, with a yield strength of 140,000 psi, this nut is tough enough to handle whatever you throw at it.

When it comes to size, the wrench diameter is 1/2 in., making it easy to fit into your toolbox without taking up too much space. Just a heads up, it doesn’t come with washers, so you might want to grab those separately if you need them.

Each nut is sold individually, so you can get just what you need without having to buy a whole kit. If you're serious about your builds, this ARP nut is a solid choice that brings both style and strength to the table. Trust me, once you use these, you won’t want to go back to anything else.

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.
