The Proto B943130 is a tether-ready, 12-point 1/2-inch drive socket sized at 1-3/8 inch, featuring the TorquePlus drive configuration that engages fastener flats rather than corners for quick, secure socket engagement. The radius-corner internal design distributes contact stress over a larger surface area, minimizing slippage and reducing fastener damage — ideal for stubborn, damaged, or soft-material fasteners.
Built for demanding industrial and MRO environments, this socket's tether-ready design supports tool tethering programs for drop prevention in elevated work areas. The TorquePlus geometry shifts stress away from fastener corners, helping preserve fastener integrity even under high-torque applications.
