The Proto B941825 is a 1/4-inch drive, 3/8-inch, 6-point socket featuring the proprietary TorquePlus™ drive configuration that engages fastener flats — not corners — for quick, secure seating. The radius-corner internal design distributes contact stress over a larger surface area, significantly reducing the risk of fastener rounding and slippage.
This 7/8-long socket is ideally suited for stubborn, damaged, or soft-material fasteners where traditional sockets may fail. The TorquePlus™ geometry shifts stress away from fastener corners, making it a reliable choice for demanding industrial, MRO, and professional mechanical applications.
