The Proto B943619 is a 1/2" drive, 6-point impact socket sized 1-1/8" built for stubborn, damaged, or soft-material fasteners. The TorquePlus™ drive configuration enables quick, easy engagement to the fastener flats rather than the corners, reducing the risk of rounding or slippage.
TorquePlus™ technology features a radius-corner internal design that shifts contact area and stress away from fastener corners, distributing load over a larger surface area. This makes it an ideal choice for high-torque impact applications in industrial, MRO, and heavy-duty maintenance environments.
