If you’re diving into the world of diesel engines, you’ve probably heard of ARP. They’ve been around since 1968, and let me tell you, they know a thing or two about fasteners. These guys have taken their racing background and applied it to diesel technology, resulting in some seriously tough components. I’ve used their head studs and bolts, and I can vouch for their strength. They’re designed to handle some intense loads, which is crucial when you're pushing your engine to its limits.
Now, let's talk specifics. The ARP M10 x 1.25 x 100 SS Hex Bolts come in a pack of five, and they’re not just your run-of-the-mill fasteners. With a 12mm hex socket size, you’ll find them easy to work with. The torque value is set at 54 ft-lbs (or 73.2 Nm), which means you can really crank down on them without worry. The overall length is 100mm, and with a thread length of 26mm, you get a solid grip that ensures everything stays tight under pressure.
Speaking of grip, the grip length is 74mm with a grip diameter of 10mm, making these bolts ideal for a variety of applications. The thread diameter is M10 x 1.25mm, which is pretty standard for many setups, so you won’t have to worry about compatibility issues. Plus, the head height is 9.0mm, and the collar diameter sits at 18.5mm, giving you a robust design that can withstand the rigors of performance driving.
In short, if you’re looking for reliable fasteners that won’t let you down, these ARP bolts are a solid choice. They’re built to handle the high pre-loads that come with installation, so you can focus on what really matters—getting your rig out on the road or trail without any worries.

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.
