This comprehensive 26-piece heavy-duty socket set is engineered for professional mechanics, truck maintenance, and heavy machinery repair. Featuring both 3/4-inch and 1-inch square drive tools, it includes a wide range of jumbo metric sockets spanning from 21mm to 65mm (including the massive 55mm, 60mm, and 65mm sockets) to handle axle nuts, suspension components, and large bolts. Forged from high-strength Chrome Vanadium (Cr-V) steel with a 6-point hex design, every piece is built to withstand high torque without stripping or rounding off fasteners. The set comes neatly organized in a sturdy, custom-molded green storage case
