The Proto B943552 is a 7/8" deep impact socket with a 3/8" drive and 6-point configuration, engineered for use on stubborn, damaged, or soft-material fasteners. The TorquePlus™ internal design features a radius-corner profile that engages fastener flats rather than corners for quick, secure socket seating.
By shifting contact area and stress away from fastener corners and distributing load over a larger surface, the TorquePlus™ configuration minimizes slippage, reduces fastener rounding, and delivers high-performance torque transfer in demanding impact applications.
