Proto's 11mm Thin Wall Impact Socket features the patented TorquePlus drive design, which engages fastener flats rather than corners. The radius-corner geometry shifts contact stress away from corners and distributes it over a larger surface area, minimizing slippage and reducing fastener rounding—ideal for stubborn, damaged, or soft-material fasteners.
The thin wall construction allows access in tight spaces where standard impact sockets won't fit, while the 12-point configuration provides more engagement positions for faster socket placement. Designed for use with 1/2-inch drive impact wrenches and ratchets in professional and MRO applications.
