Proto® TorquePlus™ design is a high performance drive configuration which allows for
quick and easy engagement to the fastener flats, not the corners.
The TorquePlus™ configuration employs a radius-corner design, shifting contact area
and stress away from the fastener corners and distributing contact stresses over a
large area of the socket, minimizing slippage.
The TorquePlus™ internal design minimizes fasterner rounding, helps to extend fastener
life, and allows the user to more easily turn worn, rounded, or rusted fasteners.
Magnets feature enhanced holding power to help improve fastener retention, helping
to increase productivity.
