PROTO 19-Piece Deep Impact Socket Set, SAE

Proto 6 Point Impact Sockets are ideal for use on stubborn or damaged fasteners, and also on fasteners made from soft materials

• Design is a high performance drive configuration which allows for quick and easy socket engagement to the fastener flats, not the corners
• Internal design minimizes fastener rounding, helps to extend fastener life, and allows the user to more easily turn worn, rounded, or rusted fasteners
• 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
