The Proto B942949 1/2" drive deep socket features the proprietary TorquePlus™ design, which engages fastener flats rather than corners for quick, secure socket seating. The radius-corner internal geometry shifts contact stress away from fastener corners and distributes it over a larger surface area, minimizing slippage and reducing the risk of rounding.
Ideal for stubborn, damaged, or soft-material fasteners, this 6-point deep socket offers superior grip and control in tight or recessed applications. The 3-1/4" depth accommodates extended bolts and deep fastener access where standard-depth sockets fall short.
