This 3/8" Drive 21 Piece Metric Socket Set - 12 Point incorporates the TorquePlus wrenching system, a high-performance drive configuration that enables quick and easy socket engagement to the fastener flats, not the corners. The configuration employs a radius-corner design, shifting contact area and stresses over a large area of the socket, minimizing slippage. The internal design of the TorquePlus minimizes fastener rounding, helps to extend fastener life, and allows the user to more easily turn worn, rounded, or rusted fasteners.
