If you're diving into a project that demands some serious fastening power, you might want to check out this ARP 3/8in x 16 - 1.25in UHL 12pt Stainless Steel Bolt Kit. I've used these bolts in a few builds, and let me tell you, they don't mess around.
First off, the 3/8-16 in. RH fastener size means they're versatile enough for a bunch of applications. Whether you're working on a custom rig or just need reliable fasteners for repairs, these bolts have got your back. The 1.250-inch underhead length gives you enough grip without being overly long, so you can fit them into tight spaces without a hassle.
Now, let’s talk about the 12-point head style. It’s not just for show; this design helps prevent slippage when you're cranking down, which is crucial if you're working with high-torque applications. Made from ARP Stainless 300, the material is tough as nails and won't rust on you, even in harsh conditions. Plus, the polished finish gives them a sleek look, so they won't just perform well—they'll look good doing it.
These bolts pack a serious punch with a yield strength of 180,000 psi. Trust me, you want that kind of strength when you're putting your rig through its paces. And if you're wondering about tools, the 3/8 in. wrench diameter means you can easily find what you need to get the job done without any special equipment.
Oh, and don’t worry about hunting down washers; they’re included in the kit. You’ll get a set of 5 bolts, which is perfect for most mid-range projects or repairs. Whether you're a DIYer or a professional, these bolts will hold up to whatever you throw at them.
In short, if you're looking for durable, reliable fasteners that won't let you down, this ARP bolt kit is a solid choice. I've seen them hold up under pressure, and I think you'll be impressed with their performance, too.

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.
