Proto J7428S Includes

• (1) 1/2″ DRIVE IMPACT SOCKET 7/8″ – 8 POINT

Proto J7428S Features

• 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.
