ARP Bolts M12 Black Washers 0.995 OD Chromoly 2 Pack - Hardened, 0.120 Thickness
$1.95

If you're diving into some serious work on your ride, you’ll want to check out these ARP M12 black washers. These aren't your run-of-the-mill washers; they’re made from tough Chromoly, so you know they can take a beating. With an outside diameter of 0.995 inches (or 25.273 mm for those who prefer metric), they've got the right size to fit snugly without any unnecessary play.

Now, let’s talk specifics. The inside diameter measures 0.472 inches (12 mm), which is perfect for M12 bolts. The thickness is 0.120 inches (3.048 mm), giving you that extra bit of durability when you're tightening things down. And yeah, these guys are hardened, so they won’t deform under pressure like some of the cheaper options out there.

These washers come in a sleek black oxide finish, which not only looks good but also helps resist corrosion. They’re sold in pairs, so you can tackle whatever project you’ve got going on without scrambling for more parts. Just a heads up, there’s no chamfer on the inside diameter, but that’s just how they roll—keeping things straightforward and effective.

Whether you're working on a custom build or just need reliable hardware for routine maintenance, these washers are a solid choice. They fit perfectly for any M12 application, so you can trust they’ll deliver the performance you need. Grab a pair and get back to building!

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.
