If you're diving into a project that demands reliability and strength, these ARP 5/16-24 x 1.000 12pt Black Oxide Bolts are worth your attention. Trust me, I’ve put these bad boys through their paces, and they’ve never let me down.
First off, let’s talk about the build. These bolts are made from chromoly, specifically the ARP 8740 grade, which is known for its incredible strength and durability. With a yield strength of 180,000 psi, you can bet they’ll hold up under pressure. Whether you’re working on a high-performance engine or just need something solid for your custom rig, these bolts are up for the task.
The 12-point head style is a game-changer, allowing for a better grip and more torque than your standard hex bolts. Plus, the black oxide finish not only looks sharp but also helps resist corrosion—an essential feature if you’re in a humid environment or hitting the trails.
What’s even better? They come with washers included, so you won’t have to hunt around for the right fit when you’re ready to install. Each set includes five bolts, which is perfect for most applications without leaving you with a bunch of extras lying around.
With a wrench diameter of 3/8 in., these bolts fit nicely in your toolbox without taking up too much space. They’re designed to make your life easier, whether you’re a weekend warrior or a full-time fabricator. If you’re serious about your builds, you’ll want to have these in your arsenal.
In short, if you’re looking for reliable fasteners that won’t let you down, these ARP bolts are a solid choice. They’ve got the specs to back them up, and I can personally vouch for their performance. Give them a shot—you won’t regret it.

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.
