Proto J1221M-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.
  • Metric sizes 9mm and smaller do not have 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.
