ARP Bolts M8 x 1.25 x 25mm 12pt Stainless Steel Bolts (5/pkg) with Washers Included - 771-1002

If you're diving into a project that requires some serious fastening power, let me tell you about these ARP M8 x 1.25 x 25 12-point stainless steel bolts. I’ve had my hands on these bad boys, and they really know how to hold things together.

First off, the fastener size is 8mm x 1.25 RH, which is pretty standard for a lot of applications, so you shouldn't have any trouble finding a spot for them. The underhead length comes in at 25mm, giving you just the right amount of grip without being overly bulky. And let’s not forget the 12-point head style—it’s not just for looks. This design allows for better torque and makes it easier to get a wrench in there, especially in tight spaces.

These bolts are made from ARP Stainless 300, which means they’re tough. The yield strength is impressive, sitting at a hefty 180,000 psi. That’s some serious muscle for whatever you're bolting down. Plus, they come polished, so they not only perform well but look good doing it.

When it comes to installation, you’ll be using a 10mm wrench—no need to dig through your toolbox for the right size. And yeah, they come with washers, so you’re all set right out of the package. Speaking of packaging, these bolts are sold as a set of five, which is perfect for most jobs without leaving you with a bunch of extras lying around.

Overall, if you need reliable, high-strength fasteners that won’t let you down, these ARP bolts are a solid choice. They’ve served me well, and I’m sure they’ll do the same for you.

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.
