The Proto 12-Point Deep Socket features the TorquePlus™ drive configuration, which engages fastener flats rather than corners. Its radius-corner internal design shifts contact stress away from corners and distributes it over a larger area, minimizing slippage and reducing fastener damage — ideal for stubborn, damaged, or soft-material fasteners.
Tether-ready design supports tool-tethering safety programs in elevated or critical work environments. At 2-1/8 inches long, this deep socket provides the reach needed for recessed or extended fasteners in industrial, MRO, and professional mechanical applications.
