Proto J1232MASD 32mm 12-Point Metric ASD Combination Wrench

Proto J1232MASD 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.
• 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 and sizes 36mm and larger 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.
