The Proto B943122 is a 1/2-inch drive, 12-point socket sized 3/4-inch with a 1-1/2-inch length, featuring the proprietary TorquePlus™ design that engages fastener flats rather than corners. This radius-corner configuration distributes contact stress over a larger area, minimizing slippage and reducing the risk of rounding fasteners — making it ideal for stubborn, damaged, or soft-material fasteners.
Built tether-ready for use in height-safety and tool-drop-prevention applications, this socket is well-suited for industrial, MRO, and professional trades environments where tool retention is critical. The 12-point configuration provides more engagement positions for easier access in confined or awkward spaces.
