ARP M6 x 1.00 x 25 Black Oxide Hex Bolts, Chromoly, 5-Pack, 180,000 psi Yield Strength - 660-1002

If you're diving into a project that demands some serious strength, these ARP M6 x 1.00 x 25 Black Oxide Hex Bolts are the real deal. I’ve used these bolts on a few builds, and let me tell you, they hold up like a champ. Made from chromoly, these bad boys are tough enough to take whatever you throw at them. We're talking about a yield strength of 180,000 psi, which means they can handle some serious stress without breaking a sweat.

The hex head design makes it easy to get a solid grip with an 8mm wrench, so you won't be fumbling around trying to get them tightened down. And the black oxide finish? Not just for looks—this finish helps protect against corrosion, which is a must if you’re working in any kind of harsh environment.

Each set comes with five bolts, so you’ll have enough to tackle a decent-sized job. Plus, they come with washers included, which is a nice touch that saves you a trip to the hardware store. The underhead length of 25mm gives you the right amount of reach for most applications, making these bolts a versatile choice for any enthusiast or small shop owner looking to beef up their setup.

In short, if you want reliable fasteners that won't let you down, these ARP bolts are a solid investment. They’ve become a staple in my toolbox, and I can’t recommend them enough for anyone who’s serious about 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.
