perfectly sealed to the intake manifold is through the use of
ARP's carburetor studs, which features J-form threads to resist
loosening from vibration. They're offered in a variety of heights
to accommodate most any combination of carburetor and space.

One of the most critical, yet often overlooked, fasteners used in any engine
locks the timing in place. ARP offers these premium grade studs, which are
equipped with vibration-resistant J-form threads, in black oxide finished chrome
moly or rust-proof stainless steel. A special bullet nose helps guide nut into
place without cross-threading. Choice of conventional 6-point or space-saving
12-point nuts. Washers included.

As the crankshaft flexes and twists, the damper
absorbs incredible amounts of kinetic energy. To ensure that
the damper is locked in position, ARP has developed these
ultra strong 190,000 PSI bolts that let you exert maximum
clamping force. Special features include 1/4" thick, wide area washer.
Big Block Chevy 4 bolt - HP Series Hex Bolts
There are many important reasons to use ARP main stud kits, including the elimination
of main cap walk and fretting, as well as protecting the threads in your engine block.
The studs are manufactured in our own factory using the best materials, processes,
designs and engineering. Every ARP main stud kit exceeds the most stringent aerospace
specifications. All kits come complete with hardened parallel-ground washers and
aerospace quality nuts. Some applications have provisions for mounting windage trays and
have specially designed standoff studs with serrated lock nuts to position the windage tray
and lock it securely in place. The studs are manufactured from 8740 chrome moly steel,
heat-treated in-house to 190,000 PSI tensile strength, and precision J-form threads rolled
after heat-treat to create a fastener that has threads 1000% stronger than others. Don't
settle for anything less than the best. Insist on genuine ARP studs . . . you'll find the
name stamped right on the end!
