•Drive end chamfer and four detents help provide quick positive engagement with drive tool on any of the socket drive walls. •Tight tolerances for snug fit on fastener. •Large clearance holes, concentric opening and nut end chamfer make it easy to position socket on fasteners. •Made from high strength steel to help minimize wall thickness and provide access to fasteners in recesses and where nuts and bolts protrude. •Impact sockets are used wherever powered drive tools are used to install or remove fasteners. •Impact sockets are designed to withstand higher torque and force associated with impact tools in repetitive application. •Proto® 8 Point Impact 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 size stamped on tool for easy identification. •Side locking hole.
