ARP Bolts M10 Black Chamfer Washer 0.850in OD Chromoly Hardened Single Washer - 200-8590

If you're diving into a project that requires some solid hardware, let me tell you about the ARP M10 Black Chamfer Washer. This little guy is a game-changer when it comes to ensuring everything stays tight and right on your ride. We're talking about a washer that measures in at 0.850 inches for the outside diameter and 0.394 inches for the inside. For those who prefer metric, that’s about 21.590 mm and 10.007 mm respectively. Pretty handy, right?

Now, let's get into the nitty-gritty. This washer is 0.120 inches thick (or about 3.048 mm), which gives it some serious heft. It’s made from chromoly, so you know it’s tough. The black oxide finish not only looks slick but also helps resist corrosion, making it a solid choice for any project where durability is key. Plus, it’s hardened, so you can trust it won’t just bend or break under pressure.

One thing to keep in mind: these washers are sold individually, so if you need a few, make sure to grab enough for your setup. And while it doesn’t have an inside diameter chamfer, that just means it’s straightforward and ready to do its job without any frills.

Whether you’re upgrading your suspension, working on a custom build, or just doing some routine maintenance, this ARP washer is a reliable choice that fits right in where you need it. Just make sure to double-check your specs to ensure you’re getting the right fit for your application. Trust me, you won't regret having these on hand!

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.
