If you're diving into the world of diesel performance, you’ve probably heard of ARP. They’ve been at it since 1968, and let me tell you, they know a thing or two about fasteners. These aren’t just any bolts; they’re designed to take the kind of punishment that comes with high-performance engines. I’ve seen my fair share of fasteners, but ARP's head studs and bolts, along with main studs and driveline components, are built to withstand some serious loads. It’s like they’ve taken the concept of strength and just cranked it up to eleven.
What really sets these ARP 10-24 x .500 12pt stainless steel bolts apart is their installation pre-load. When you’re putting these bad boys in, you’re stretching them to the max, which means they hold tight under pressure. That’s crucial when you’re pushing your diesel to its limits. You want to know that everything is locked down and ready to handle whatever you throw at it.
Now, let’s get into the nitty-gritty of the specs. These bolts come with a socket size of 1/4 12pt, which fits nicely in your toolbox. The torque value is something you’ll want to pay attention to—make sure you’ve got the right tools to get that perfect fit. The overall length (UHL) is 0.500", with a thread length of the same, so you know it’s designed for a snug fit. The thread diameter is 10-24, which is pretty standard, but don’t let that fool you; these are anything but average.
The grip length is zero, which means they’re meant for direct application without any extra bulk. And with a head height of 0.365", they fit well in tight spots. The wrenching area is a nice 0.260", giving you enough leverage to really torque them down. You won’t find any unnecessary collar diameter here, just straightforward, reliable design.
In short, if you’re looking to upgrade your diesel setup, these ARP bolts are a solid choice. They’ve been tested in the real world and have proven themselves time and again. Trust me, you’ll feel the difference when you’re on the road or hitting the trails.

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.
