ARP 200-8593 5/16" ID .550" OD Chromoly Washer, Black Oxide Finish, Sold Individually - 200-8593

If you're diving into some serious Jeep upgrades or just need a reliable washer for your next project, the ARP 5/16 ID .550 OD Washer is worth a look. This little piece packs a punch in terms of quality and durability. With an outside diameter of 0.550 inches (or about 13.970 mm), it’s designed to fit snugly where you need it.

Now, let’s talk about the inside diameter. At 0.312 inches (around 7.924 mm), it’s perfect for those specific applications where precision matters. And with a thickness of 0.120 inches (3.480 mm), it strikes a nice balance between strength and weight, which is crucial when you’re out on the trails or working on your rig.

What really sets this washer apart is its chromoly material. It’s tough as nails, which means it can handle a lot of stress without warping or breaking. Plus, the black oxide finish not only looks sleek but also provides some added corrosion resistance. No one wants to deal with rust when you’re trying to keep your ride in top shape.

One thing to note is that this washer isn’t chamfered on the inside diameter, so if you’re looking for something with that feature, you might want to keep searching. But if you’re after something hardened and reliable, this washer has got you covered. Just remember, it’s sold individually, so grab a few if you need more for your project.

In short, whether you're a weekend warrior or a daily driver, this ARP washer is a solid choice for keeping your components secure and functioning smoothly. It’s the kind of part you can trust to hold up under pressure.

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.
