NEIKO 02437A 1/4 in. Drive Master Impact Socket Wrench Set combines versatility and durability for both automotive and heavy-duty applications. This 54-piece set includes deep and standard SAE and metric sockets, featuring easy-to-read laser-etched markings for quick identification. Each socket is made from drop-forged CrV steel with a phosphate coating for protection against oil, dirt, and corrosion, and the 6-point hex design minimizes rounding and damage. The low-profile 5-7/16 in. ratchet with 72-tooth gearing allows for smooth operation in tight spaces, while the set's impact-rated extensions, universal joint, and 3/8 in. to 1/4 in. reducer provide access to hard-to-reach fasteners. Included are 3 in. and 8 in. impact extension bars and a 360° rotational U-joint for maximum flexibility. All pieces are housed in a blow-molded case with designated slots and secure levers to prevent loss during transport. Ideal for mechanics, DIY enthusiasts, and construction professionals, this complete socket set ensures efficiency, reliability, and ease of use in any workshop or job site.
