The Proto B943145 1" Drive Deep Impact Socket features the patented TorquePlus™ design, a high-performance drive configuration that engages fastener flats rather than corners. The radius-corner geometry shifts contact stress away from fastener corners and distributes it over a larger surface area, minimizing slippage and reducing fastener rounding — ideal for stubborn, damaged, or soft-material fasteners.
With a 3-3/4" deep length and 6-point configuration, this impact socket provides exceptional reach for recessed or deeply set fasteners in industrial, MRO, and heavy-duty applications. Built by Proto to withstand the demands of power impact tools while protecting fastener integrity on every job.
