Proto J1218-T500 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.
• Anti-Slip Design (ASD) open end
  -Patented locking grooves help prevent the wrench from slipping off the fastener when turning
  -The arched surfaces are designed to spread the contact forces over a greater area
  -Loads are kept off the corners of the fastener which helps prevent fastener rounding
• Fractional sizes 11/32″ and smaller do not have the ASD feature
• 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
