If you're diving into a Pontiac project, you know that every little detail matters, especially when it comes to the thermostat housing. That’s where the ARP Pontiac SS Hex Thermostat Housing Bolt Kit comes into play. These aren't just any bolts; they're made with a level of precision and quality that you can trust.
First off, let’s talk about the fastener style. You’re getting a solid bolt here, which means you can count on a secure fit that won't let you down when you're out on the road or tearing up the track. With an underhead length of 1.000 inches, these bolts are designed to fit snugly without any fuss. No weird gaps or misalignments—just clean, reliable installation.
The hex head style is a nice touch too. It makes tightening and loosening a breeze, especially in those tight spots where you don’t have a ton of room to maneuver. Plus, the stainless steel material means you’re not just getting something that looks good; you’re getting durability that can withstand the elements and resist rust. And let's be honest, no one wants to deal with corroded bolts when they're just trying to enjoy their ride.
Speaking of looks, the polished finish adds a bit of flair under the hood. It’s those little details that can make a big difference in how your engine bay presents itself, and trust me, it’s nice to have something that shines just a bit while still being tough as nails.
So, if you're gearing up for a rebuild or just need to replace some worn-out hardware, this kit is a solid choice. It’s all about quality and performance here, and these bolts deliver on both fronts. You’ll appreciate the ease of installation and the peace of mind that comes with knowing you’ve got the right parts to keep your Pontiac running smoothly.

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.
