Proto J1270B 4 Pc. Flex Head Wrench Set - 12 Point

Proto J1270B Features

• Satin finish provides corrosion resistance and a slip resistant grip
• 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
