Proto J1218BASD Features

• Non-reflective ProtoBlack finish for use where non-plated products are required.
• 12 point box end allows for fine indexing, helping to improve speed and access. Fits 4, 6 and 12 point fasteners.
• The box end is countersunk for easy application to the fastner.
• 15 angled offset box end helps keep shank clear of obstructions.
• Inch sizes 1-5/16″ and larger 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.
