ARP Bolts M8 x 1.25 Pitch Black Oxide Hex Bolts 100mm UHL 10mm Wrench (5/pkg) - 661-1015

If you're diving into some serious engine work or just need to replace a few bolts, let me tell you about these ARP M8 bolts. They're not your average fasteners; we're talking about some robust, high-quality pieces that can really hold their own. Each bolt is 8mm with a 1.25 pitch and a solid underhead length of 100mm. That means they’re built for strength and reliability.

These hex head bolts are made from ARP 8740 chrome moly, which is a fancy way of saying they’re tough as nails. With a yield strength of 180,000 psi, you can trust that they’ll keep everything locked down tight even under serious stress. Plus, the black oxide finish not only looks slick but also adds a layer of protection against rust and corrosion.

You'll need a 10mm wrench to get these bad boys on, and don’t worry, they come in a set of five, so you’ve got enough to tackle most jobs without scrambling for extras. Oh, and they even include washers, which is a nice touch. Whether you’re bolting down components in a performance build or just doing some routine maintenance, these ARP bolts are a solid choice. They fit perfectly when you need that extra peace of mind in your setup.

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.
