ARP M8 x 1.25 x 35 Black Oxide Hex Bolts, Chromoly, 5-Pack, 180,000 psi Yield Strength - 661-1004

So, you’re diving into some serious upgrades for your ride? Let me tell you about these ARP M8 x 1.25 x 35 Black Oxide Hex Bolts. If you’re looking for fasteners that can handle the heat and pressure, you’ve found the right ones. These bad boys are made from ARP 8740 chrome moly, which is a fancy way of saying they’re tough as nails. Seriously, with a yield strength of 180,000 psi, you can trust them to keep everything locked down tight, even when you're pushing your engine to the limit.

Now, let’s talk dimensions. Each bolt has an underhead length of 35mm, and they come with a hex head style that makes it easy to get a solid grip while you’re wrenching away. You’ll need a 10mm wrench to get these on, and don’t worry, washers are included in the package to ensure a snug fit. And since they come in a set of five, you’ll have just what you need for those key areas that require a little extra strength.

The black oxide finish not only looks slick but also adds a layer of corrosion resistance, which is a lifesaver if you’re out there battling the elements. Whether you're hitting the trails or just cruising around town, these bolts are built to last and won’t let you down. So, if you want to make sure your setup is rock solid, grab a set of these ARP hex bolts. You won't regret it.

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.
