Since 1968, ARP has been pushing the boundaries of fastener technology, especially in the world of racing and heavy-duty applications. If you're working on a diesel engine, you know how important it is to have reliable fasteners. These ARP 5/16-24 x .560 Hex Black Oxide Bolts are designed to handle some serious stress, making them a solid choice for anyone looking to beef up their setup.

What sets these bolts apart? Well, they’re built to withstand extreme loads, which is a game changer when you’re pushing your engine to its limits. The high installation pre-load means you're getting a tight fit right off the bat, so you won't have to worry about them loosening up over time. Whether you’re replacing old bolts or doing a full rebuild, these are the kind of fasteners you can count on.

  • Socket Size: 3/8 hex
  • Torque Value: 24 ft-lbs (32.5 Nm)
  • UHL: 0.560"
  • Thread Length: 0.560"
  • Thread Diameter-Pitch: 5/16-24
  • Grip Diameter: 5/16"
  • Wrenching: 3/8"
  • Head Height: 0.300"
  • Collar Diameter: 0.620"

These bolts are not just any bolts—they're made with a black oxide finish that adds a layer of protection against corrosion. If you’re in an environment where rust is a concern, this finish will help keep your fasteners looking good and performing even better. Plus, the 5/16-24 thread size fits a variety of applications, so you can use them in different setups without worrying about compatibility.

In short, if you want fasteners that can take a beating and keep on performing, these ARP bolts are a no-brainer. They’re built for the long haul, and whether you're hitting the track or just need something reliable for your daily driver, you won't be disappointed.

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.
