ARP Bolts M12 x 1.75 x 35 Hex Black Stainless Steel Bolts 14mm Socket (5/pkg)
$29.95

If you're diving into the world of performance diesel engines, you’ve probably heard of ARP. These guys have been at it since 1968, pushing the envelope on fastener design and manufacturing. I’ve had my fair share of experiences with their products, and let me tell you, their fasteners are no joke. We're talking about head studs, main studs, and driveline bolts that are built to take on some serious stress. Whether you're racing or just looking to beef up your rig, these fasteners are designed to handle the extreme loads that come with high-performance setups.

One of the standout features of these ARP M12 x 1.75 x 35 Hex Black Stainless Steel Bolts is their impressive installation pre-load. When you install them, you’re stretching them quite a bit, which means they hold tight and won’t back down under pressure. I’ve used them in my own builds, and I can vouch for their reliability. You can really feel the difference when you’re wrenching on them.

Now, let’s get into the nitty-gritty. These bolts come with a 14mm hex socket size, which makes them pretty standard for most setups. When it comes to torque, you’ll want to crank them down to about 98 ft-lbs (or 132.9 Nm if you’re into metric). The under head length is 35mm, and the thread length is 30mm, which gives you a solid grip. Speaking of grip, they have a 5mm grip length and a thread diameter of M12 x 1.75mm, so you know they’re going to fit snugly where you need them.

In terms of dimensions, the grip diameter is 12mm, and the head height is 11.7mm, fitting perfectly in tight spaces. The collar diameter is 21.6mm, which adds to their robust design. You get five of these bad boys in a pack, so you’ll have what you need for your next project without breaking the bank.

In short, if you’re serious about your diesel performance, these ARP bolts are a solid choice. They’ve got the strength and reliability you need, and I can’t recommend them enough based on my own hands-on experience.

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.
