ARP Pro Series ARP2000 studs are centerless ground and heat treated prior to thread rolling and machining, with a nominal 220,000 psi rating. Compared to OEM torque-to-yield (TTY) bolts, they offer a 40% increase in tensile strength.

These fasteners are precision centerless-ground and thread-rolled to Mil-S-8879 specifications, and finished in black oxide to help protect against wear and corrosion.

Each kit includes hardened parallel washers to promote even load distribution and more consistent torque readings.
