The Proto B941806 is a 3/4" drive, 20mm, 12-point socket featuring the TorquePlus™ drive design — a high-performance configuration that engages fastener flats rather than corners. The radius-corner geometry shifts and distributes contact stress over a larger surface area, minimizing slippage and reducing the risk of rounding fastener heads, making it ideal for stubborn, damaged, or soft-material fasteners.
At 2" long, this deep-reach socket provides clearance for recessed or extended fasteners encountered in industrial, MRO, and automotive applications. The 12-point configuration allows for quick engagement and is especially effective where swing arc is limited or precise torque application is required.
