The Proto B943217 is a 1/2" drive, 22mm 6-point metric socket engineered with the TorquePlus™ design — a high-performance drive configuration that engages fastener flats rather than corners, allowing for quick, secure socket seating. The radius-corner design shifts contact stress away from fastener corners, distributing load over a larger surface area to minimize slippage and reduce the risk of rounding.
Ideal for use on stubborn, corroded, or damaged fasteners, as well as fasteners made from soft materials, this 1-17/32" long socket delivers reliable torque transfer in demanding industrial, MRO, and professional applications. The 6-point geometry provides maximum contact and control compared to 12-point alternatives.
