Full polish finish provides corrosion resistance and easy to clean surfaces.
12 point box end allows for fine indexing, helping to improve speed and access. Fits 4, 6 and 12 point fasteners.
Offset box end allows access to recessed fasteners and keeps hands clear of obstructions.
Box ends incorporate the TorquePlus system.
Proto TorquePlus wrenches are ideal for use on stubborn or damaged fasteners, and also on fasteners made from soft materials.
The TorquePlus design is a high performance drive configuration which allows for quick and easy wrench 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 box end, minimizing slippage.
The TorquePlus internal design minimizes fastener rounding, helps to extend fastener life, and allows the user to more easily turn worn, rounded, or rusted fasteners.
