The Proto B943303 is a 1/2" drive, 6-point metric socket in 30mm size, engineered with the patented TorquePlus™ design that engages fastener flats rather than corners. This radius-corner configuration shifts contact stress away from vulnerable fastener edges, distributing load over a larger surface area to minimize slippage and reduce the risk of rounding.
Ideal for use on stubborn, damaged, or soft-material fasteners, this socket delivers high-performance torque transfer and quick, reliable engagement. The 1-25/32" length provides the reach needed for a wide range of industrial, MRO, and mechanical applications.
