ARP Automotive: Ensuring the Finest Automotive Fasteners to Withstand Extreme Pressure | EBS Racing
A chain is only as strong as its weakest link, and that same
principle holds true for fasteners. If you’re building a high-powered engine,
the bolts and studs have to be able to withstand extreme pressure. That’s why
EBS Racing has teamed with ARP Automotive Products, and now stock their entire
line of Porsche related race-quality bolts and studs. An engine is only as
strong as its weakest bolt, and we don’t use anything but the best in our
engine builds. You should too.
What Makes a Strong
Fastener?
Design
Typically, automotive fasteners are designed to meet industry
standards for stress and torque load. But ARP goes beyond the accepted
standards, engineering each nut, stud and bolt for its specific application.
This is done with lots of math, and clever engineering like reducing the number
of necessary threads in order to reduce fatigue stress. Lots of thought goes
into each ARP fastener, which means you can just put the hammer down and not
worry about your car, or your engine coming apart.
Metal
The strength of a fastener is not only affected by its design,
but also by the metal it’s made of. Most automakers use stainless steel nuts
and bolts to hold their vehicles together. And this is perfectly fine for the
average driver. ARP even makes stainless steel fasteners, which are ideal for
repairs and restorations. But if you want your Porsche to be strong enough to
handle anything, ARP makes automotive fasteners that offer up to double the
tensile strength of normal nuts and bolts.
Available ARP
Automotive Fastener Types
Stainless Steel:
Perfect for restoration and repairs. ARP “Stainless 300” polished stainless
steel fasteners resist rust and corrosion, while providing a tensile strength
rating of up to 170,000 psi.
8740 Chrome Moly:
Referred to as a ‘quench & temper steel’, this heat-treated steel alloy has
higher fatigue resistance than ordinary stainless steel. And its
180,000-210,000 psi tensile strength makes it ideal for moderate-stress racing
applications.
ARP2000®:
ARP2000 is a proprietary alloy steel that’s heat treated to produce a material
with higher tensile strength than 8740 chrome moly. It provides a clamp load of
220,000 psi, which makes it perfect for short-track and drag racing
applications. ARP2000 fasteners also provide superior resistance to stress
corrosion and hydrogen embrittlement.
L19: If your
Porsche is going way beyond what Stuttgart intended, then ARP L19 fasteners are
what you’re looking for. This is premium steel can deliver a clamp load of
260,000 psi, but it must be kept moisture-free and well lubricated.
Aermet®:
One step above L19 is Aermet, a super-alloy with an incredible tensile strength
of 290,000-310,000 psi. Developed for the high-stress loads of top fuel and
funny car racing, Aermet is the ideal metal for extreme applications. But it
must be kept well-lubricated and moisture free.
Inconel 718:
Designed for extreme high & low temperature applications (like rally cars),
this nickel-based metal provides 210,000-230,000 psi tensile strength...no matter
what Mother Nature throws at you.
ARP3.5®
(AMS5844): Originally developed for aerospace applications and jet engines,
ARP3.5 fasteners are widely used in NASCAR, IRL and Formula 1. This high-cobalt
material provides incredible fatigue resistance, and a tensile strength range
of 260,000-280,000 psi.
Custom Age 625 Plus®:
Optimized to resist corrosion and oxidation, this super-alloy offers superior
tensile strength of 260,000-280,000 psi, making it ideal for a number of
extreme applications.
Titanium: Available for special order, ARP titanium fasteners not only offer superior corrosion resistance, but they’re 40% lighter than a comparable steel fastener. Whether you’re building a jet...or a Really fast Porsche, then ARP & EBS Racing has you covered.
ARP History
In 1968, a man named Gary Holzapfel started ARP in his
backyard garage. He was a racing enthusiast with many friends on the SoCal
racing circuit. After watching many of his friend’s engines blow-up due to
broken bolts and studs, Gary decided to do something about it. Drawing on his
experience as an aerospace fastener designer, he developed a line of automotive
fasteners that could actually withstand the extreme pressures that are created
by racing engines.
