Proto® J5212 Standard Length Drive Socket, Imperial, 3/8 in 12 Point Socket, 3/8 in Square Drive

• The TorquePlus™ design is a high performance Drive configuration which allows for quick and easy socket engagement to the fastener flats, not the corners
• The TorquePlus™ 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 TorquePlus™ internal design minimizes fastener rounding, helps to extend fastener life and allows the user to more easily turn worn, rounded or rusted fasteners

For use on stubborn or damaged fasteners and also on fasteners made from soft materials

Standard/Approvals: ASME B107.110-2012, AS954E S3.8.1
