• (1) SOCKET BAR, 11"
• (1) SOCKET CLIP, 3/8" DR
• (21) TETHER-READY HAND SOCKETS

FEATURES:
• 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.
• Proto® 12 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.
