If you’re in the market for some serious hardware, let me tell you about these ARP M8 x 1.25 x 60 12-point black oxide bolts. These aren’t just any bolts; they’re made from top-notch chromoly material, which means they’re built to last. Seriously, you can feel the difference. With a yield strength of 180,000 psi, you know these bad boys can handle the pressure. Whether you’re tightening things down on your race car or just need something reliable for your weekend project, these bolts have got you covered.
Now, let’s talk specifics. The fastener size is 8mm x 1.25 RH, and the underhead length is 60mm. That’s a sweet spot for a lot of applications. Plus, they come with a 12-point head style, which gives you a bit more grip than your standard hex head. You’ll appreciate that when you’re working in tighter spaces or just want to avoid stripping the head.
These bolts come with washers included, making installation a breeze. And since they’re sold as a set of 5, you won’t have to worry about running out midway through your project. The black oxide finish not only looks slick but also helps prevent corrosion, so you can trust that they’ll hold up over time.
In short, if you want a solid set of bolts that can take a beating and keep your build secure, these ARP bolts are a no-brainer. They’re reliable, tough, and perfect for anyone who takes their work seriously.

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.
