Harmonic Crankshaft Rotation Bolt 7/16"-20

This ultra-strong bolt is constructed from heat-treated 8740 chromoly steel and boasts a tensile strength of 200,000 psi, ensuring it can withstand the significant kinetic energy absorbed by the balancer. Featuring a 7/16"-20 bolt thread and a 2.470" under-head length, this ARP bolt is designed for optimal fit and function. Its unique 1/2" square drive forged into the bolt head allows for simple rotation of the crankshaft with any standard 1/2" drive ratchet or breaker bar, simplifying engine assembly and servicing. The bolt is finished with a heavy-duty black oxide coating for durability and corrosion resistance. It includes a 1/4" thick wide area washer for even load distribution.
