Moroso Balancer Bolt Small Block Chevy

Balancer Bolt: The thicker 3/4" hex head on this 7/16"-20 x 2-1/4" Balancer Bolt provides a larger contact surface for more positive socket engagement. Especially important when crankshaft is being rotated by hand with the use of a socket and power bar or ratchet handle. Manufactured of Grade 8 steel with gold iridite finish.

Ultimate-Duty Balancer Bolt: Extra-strength chrome moly steel bolt with large, built-in washer flange exerts 190,000 psi of clamping force to secure balancer firmly in place under severe conditions. Unlike other brands, the bolt is machined and thread rolled after heat treating for superior strength, accuracy and longevity. Extra-tall 12-point head accepts deep 5/8" socket to provide positive grip for removal/installation without stripping. Large, 2" diameter washer is 1/4"-thick and machined perfectly flat to spread the fastening load over a larger surface area. Black oxide finish.
