The Snap-on 3/4" Drive Set, No. 414AHD, provides technicians with a complete socket set for tackling difficult heavy duty jobs. Snap-on sockets utilize the Flank Drive Wrenching System which increases torque up to 20 percent while helping to prevent the rounding of fasteners, according to the company. The chrome set features 15 tools, including 12-point shallow sockets, 8" and 16" extensions, ratchet and breaker bar heads and a handle. A storage tray is included for easy access.
