Stanley A3720 Half Inch Drive 6 Point Deep Socket

Stanley A3720 is a 1/2-inch drive, 6-point deep socket manufactured by Stanley Tools. Its deep-well geometry provides extra clearance behind the fastener head, enabling access to fasteners in tight spaces where a standard socket may not reach. The six-point opening grips hex fasteners across the flats, distributing torque more evenly and helping resist rounds when paired with a 1/2-inch drive ratchet or similar tool. Built to the tolerances of Stanley's socket line, the A3720 is designed for compatible 1/2-inch drive tooling, offering reliable performance in professional workshops and among serious DIY enthusiasts working in confined spaces. This socket is part of Stanley's standard range of hand tools, intended to deliver dependable, repeatable operation with common 1/2-inch drive equipment across a variety of mechanical and maintenance tasks.
