The Proto B943011 1/2-inch drive deep socket features a 12-point Torque Plus design engineered for quick and easy engagement to fastener flats rather than corners. This radius-corner configuration shifts contact stress away from fastener corners, distributing load over a larger surface area to minimize slippage — making it ideal for stubborn, damaged, or soft-material fasteners.
Finished in black oxide, this deep socket is built for professional MRO and industrial applications where reach and durability are critical. The Torque Plus internal geometry reduces the risk of rounding fasteners, extending both socket and fastener life on demanding jobs.
