The Proto 6-Point Socket features the patented TorquePlus™ drive configuration, engineered to engage fastener flats rather than corners. This radius-corner internal design shifts contact stress away from fastener corners and distributes it over a larger surface area, dramatically reducing slippage and minimizing fastener rounding — ideal for stubborn, damaged, or soft-material fasteners.
Sized at 16mm and built for 1/4" drive tools, this socket offers quick and easy engagement with reliable torque transfer in tight spaces. A trusted choice for professional mechanics and MRO technicians who demand precision and durability from their hand tools.
