Proto J1258B 1-13/16 ProtoBlack™ 12-Point Combination Wrench

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.
