ARP M8 x 1.25 x 100mm 12pt Black Oxide Chromoly Bolts, 5-Pack, 180,000 psi Yield Strength - 671-1015

If you’re looking to beef up your setup, these ARP M8 x 1.25 x 100 12-point black oxide bolts are a solid choice. Seriously, these aren’t your average fasteners. Made from ARP 8740 chrome moly, they pack a punch with a yield strength of 180,000 psi. That’s some serious muscle for whatever project you’ve got in mind.

Each bolt measures 100mm in length, which gives you plenty of room to work with, and the 12-point head style means you'll get a better grip when you're cranking them down. Plus, the black oxide finish not only looks sleek but also offers a layer of protection against corrosion—always a bonus when you're dealing with the elements.

And don’t worry about hunting for washers; they come included in the set of five. Whether you're upgrading your suspension, securing components, or just looking to replace some worn-out hardware, these bolts will do the trick. Just remember, they’re an 8mm x 1.25 RH fastener, so make sure you’ve got the right tools on hand—10mm wrench diameter, in case you’re wondering.

In short, these bolts are tough, reliable, and ready to handle whatever you throw at them. Perfect for anyone who appreciates quality and strength in their builds.

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.
