ARP Bolts 7/16 ID Black Chromoly Washers 1in OD, 10 Pack, Hardened, 0.120in Thick - 200-8748

If you’re diving into a project that needs some solid washers, you might want to check out these ARP 7/16 ID 1in OD Black Washers. I’ve used them on a couple of builds, and they’ve held up like champs. Each washer measures about 0.995 inches across the outside and has an inside diameter of 0.438 inches—perfect for those tighter spots where you need a reliable fit.

What really stands out is the material. These bad boys are made from chromoly, which is known for its strength and durability. Seriously, it’s like the tough guy of the washer world. The black oxide finish not only gives them a sleek look but also adds a layer of protection against corrosion, which is a bonus if you're working on something that sees the elements.

With a thickness of 0.120 inches, they provide just the right amount of support without being overkill. And if you’re worried about them bending or breaking under pressure, don’t be—these washers are hardened, so they can take a beating. Plus, they come in a set of 10, so you’ll have enough to tackle multiple projects or keep some spares on hand for the next time you’re under the hood.

All in all, if you’re looking for reliable washers that won’t let you down, these ARP ones are worth considering. 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.
