Hey there, fellow gearheads! If you're diving into the world of diesel performance, you’ve probably heard of ARP. They’ve been in the fastener game since 1968, and let me tell you, they know their stuff. These aren’t just any bolts and studs; they’re built to withstand the kind of stress that would make lesser fasteners crumble. We're talking about head studs, main studs, and driveline bolts designed to handle the extreme loads that come with high-performance diesel engines.
Now, let’s chat about the ARP 200-8636 7/16in-20in Hex Nut Kit. This little gem comes in a 10-pack, so you’ll have plenty on hand for your next project. The socket size is 11/16 hex, which means you’ll need the right tools to get these bad boys on and off. Trust me, you don’t want to skimp on quality when it comes to your engine's fasteners—these nuts are designed for serious durability and reliability.
What’s really cool about these fasteners is that they come with a high installation pre-load. Basically, that means when you install them, they stretch a bit, which helps maintain a tight fit even under heavy loads. This is crucial if you're pushing your diesel to the max, whether it’s towing, racing, or just enjoying the open road. You want to know that your engine’s held together with the best, right?
So, if you're looking to beef up your setup and ensure everything stays tight under pressure, grab this nut kit. It’s a solid choice for anyone who takes their diesel performance seriously. Just make sure you’ve got the right tools, and you’ll be set!

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.
