Proto® J54103 1/2 Drive 15 Piece Deep Socket Set - 6 Point Made in USA. Proto® 6 Point Sockets are ideal for use on stubborn or damaged fasteners, and also on fasteners made from soft materials. 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.Socket Set, Deep Length, Drive Size 1/2 In, SAE, Number of Pieces 15, Socket Type 6 Pt Deep, Sockets Included 6 Pt.
