With a 24 mm hex and a ½" (12.7 mm) drive, this harmonic balancer socket is designed with more than three times the mass of standard sockets to direct more energy toward removing the bolt. Constructed from heat-treated, impact-quality alloy steel, it fits GM LS engines and other applications that require a 24 mm pulley damper bolt.
