Proto J1100S-M Features

• 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
