The Proto B943657 1/2" drive impact socket features the patented TorquePlus™ design, a high-performance drive configuration that engages fastener flats rather than corners. The radius-corner design shifts contact stress away from fastener corners and distributes it over a larger surface area, minimizing slippage and reducing fastener damage — ideal for stubborn, damaged, or soft-material fasteners.
This 6-point impact socket is built for demanding applications where reliable torque transfer is critical. Its TorquePlus™ configuration allows for quick and easy socket engagement, making it a go-to choice for professional mechanics and industrial users working with impact wrenches and high-torque fastening tasks.
