Compliance and Restrictions



The Proto® 6-point socket set is ideal for use on stubborn or damaged fasteners, and also on fasteners made from soft materials. The TorquePlus™ drive configuration allows for a quick and easy socket engagement to the fastener flats, not the corners. Uses a radius-corner design that shifts contact area and stress away from the fastener corners and distributes contact stresses over a large area of the socket, minimizing slippage. Its internal design minimizes fastener rounding and allows the user to more easily turn worn, rounded, or rusted fasteners.
