The Proto B942920 is a 1/2-inch drive, 7/16-inch, 6-point socket featuring the Torque Plus drive configuration — a radius-corner internal design that engages fastener flats rather than corners, distributing contact stress over a larger surface area to minimize slippage and reduce fastener rounding.
Ideal for use on stubborn or damaged fasteners as well as fasteners made from soft materials, this socket's high-performance geometry allows for quick, positive engagement, making it a reliable choice for demanding professional and MRO applications.
