Harmonic Balancer Bolt – 7/16-20 in Thread – 2.470 in Long – 5/8 in 12 Point Head – Washer Included – Chromoly – Black Oxide – Small Block Chevy – Each

As the crankshaft flexes and twists, the balancer absorbs incredible amounts of kinetic energy. To ensure that the balancer is locked in position, ARP has developed these ultra strong 200, 000 psi bolts that let you exert maximum clamping force. Special features include 1/4? thick, wide area washer and an extra tall 12-point head that accepts a deep socket and eliminates the worry of stripping the head.

Now you can use premium quality ARP stainless steel or chrome moly fasteners to install most anything on a car, boat or trailer. The specially alloyed “ARP 300” stainless steel and heat-treated 8740 chrome moly bolts (black oxide finish) are nominally rated at 180, 000 psi tensile strength to provide a substantial extra margin of safety over Grade 8 hardware. What’s more, you can’t beat the gorgeous looks of ARP’s specially polished stainless steel fasteners, and their ability to resist rust. They’re truly maintenance free!
