Proto® 1/2" drive impact socket 20 mm - 6 point, 1-5/8" long proto® 6 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.
