The Proto B943893 is a 3/4" deep impact socket with a 1/2" drive and 6-point TorquePlus™ design, engineered for use on stubborn or damaged fasteners as well as fasteners made from soft materials. Its radius-corner geometry shifts contact away from fastener corners and distributes stress over a larger surface area to minimize slippage and reduce fastener rounding.
The TorquePlus™ internal configuration enables quick and easy socket engagement to the fastener flats rather than the corners, delivering high-performance torque transfer in demanding industrial, MRO, and professional applications. At 3-1/4" in length, this deep socket provides the reach needed for recessed or extended fasteners.
