The Proto 12-Point Thin Wall Impact Socket features the proprietary TorquePlus drive design, which engages the fastener flats rather than the corners for quick, secure socket seating. The radius-corner geometry shifts contact stress away from fastener corners and distributes it over a larger surface area, minimizing slippage and reducing fastener damage — ideal for stubborn, damaged, or soft-material fasteners.
Designed for use with 1/2-inch drive impact tools, the thin wall construction allows access in tight or recessed spaces where standard sockets cannot fit. Built to handle the high-torque demands of impact applications, this socket is a reliable choice for automotive, industrial, and MRO professionals.
