Cover everything from recessed fasteners to high-torque jobs with this US PRO 30-piece 1/2" drive hex bit socket set. You get the same key sizes in four useful lengths—55, 100, 140 and 200 mm—so you can choose reach without compromising drive size. Bits are manufactured from CR-V6150 / 50BV30 for durability, pressed into 1/2" drive sockets for use with ratchets, breaker bars or torque wrenches. Perfect for automotive, maintenance and assembly work where access varies from shallow to deep.
