ARP Bolts 7/16in ID Black Washer Pack of 2, Chromoly, 0.750in OD, Hardened - 200-8521

If you're diving into some serious projects or just need reliable parts for your Jeep, these ARP Black Washers are worth a look. I’ve used them on a few builds, and let me tell you, they hold up like a champ.

So, what makes these washers stand out? For starters, they’ve got a solid outside diameter of 0.750 inches (or 19.050 mm for those of you who prefer metric). The inside diameter is 0.438 inches (11.125 mm), which fits snugly on most standard bolts. They’re not just any washers; these are made from chromoly, a material that’s tough as nails and can handle the kind of stress we put our rigs through.

Thickness is another key factor—these bad boys come in at 0.150 inches (3.810 mm). That’s just enough heft to ensure they won’t warp or bend under pressure. Plus, the black oxide finish not only looks slick but also adds a layer of corrosion resistance. I’ve used them in some rough environments, and they’ve held up beautifully.

One thing to note is that there’s no inside diameter chamfer, but honestly, that hasn’t been a problem in my experience. And yes, they’re hardened, which gives them that extra durability we all appreciate when we’re out on the trail or working in the garage.

These washers come in pairs, so you’re set for your next project without having to order a bunch. Overall, if you want something that’s reliable and built to last, these ARP washers are a solid choice. Trust me, your Jeep will thank 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.
