3/8 " Drive, 1/2" SAE, Socket, 12 Points, Chrome, 1/2 in

Proto® Tethered Tool Sockets are manufactured with four detent holes so that the pin detent will engage correctly regardless of the direction the socket is placed on the square drive
The Positive Control System requires a separate tool to attach or remove the socket, meaning it cannot be removed without specific intent
Chrome finish is applied after the holes are bored for better corrosion resistance

Additional Features:

• Proto® 12 point sockets are ideal for use on stubborn or damaged fasteners, and also on fasteners made from soft materials
• The TorquePlusTM design is a high performance drive configuration which allows for quick and easy socket engagement to the fastener flats, not the corners
• The TorquePlusTM configuration employs a radius-corner design, shifting contact area and stress away from the fastener corners and distributing contact stresses over a large area of the socket, minimizing slippage
• The TorquePlusTM internal design minimizes fastener rounding, helps to extend fastener life, and allows the user to more easily turn worn, rounded, or rusted fasteners
