Proto J7421MT Features

• Proto 12 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.
