•12 point box end allows for fine indexing, helping to improve speed and access. Fits 4, 6 and 12 point fasteners. 

•Use the swiveling box end to break or cinch bolts in difficult locations. 

•Heat-treated alloy steels produce a shank with high leverage. 

•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 socket 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.
