The Proto Socket Set features a Metric drive size of 3/8 inch and includes a total of 21 pieces. This set is designed with the TorquePlus wrenching system, which offers a high-performance drive configuration for quick and easy socket engagement. The TorquePlus design employs a radius-corner design, shifting the contact area and stresses over a large area of the socket, thereby minimizing slippage.

The internal design of the TorquePlus system also helps to minimize fastener rounding, extending the life of the fasteners and allowing the user to more easily turn worn, rounded, or rusted fasteners. This socket set includes 6 standard socket point styles and does not include any deep or flex socket point styles.
